The investigation focuses on Operation Southern Spear, a campaign launched by the administration of US President Donald Trump in September 2025 targeting boats Washington alleges are linked to narcotics trafficking networks operating from Latin America.

According to reports, the Pentagon review will examine whether the US military followed established operational and legal procedures under the Joint Targeting Cycle, the framework governing the planning and execution of military strikes.

“The scope of this evaluation includes the joint process for targeted vessels in the US Southern Command area of responsibility as part of Operation Southern Spear,” the Pentagon inspector general’s office said in a memorandum cited by Bloomberg.

The review will be conducted at the Pentagon and at the headquarters of United States Southern Command in Florida, according to the memorandum dated May 11.

The military campaign has drawn criticism from legal experts and human rights organizations, which argue the strikes may constitute extrajudicial killings because the targeted vessels allegedly did not pose an imminent threat to the United States.

Critics have also questioned whether the administration has provided sufficient evidence demonstrating that the vessels destroyed during the operations were actively involved in drug trafficking.
At least 192 people have reportedly been killed since the start of the operation, according to media accounts cited in the reports.

US Defense Secretary Pete Hegseth has defended the campaign, describing the operation as part of a broader war against what the administration terms “narco-terrorists.” Hegseth previously said the operation had been so aggressive that potential maritime targets had become increasingly difficult to locate.

The strikes represent a significant shift in US counter-narcotics strategy. Historically, American anti-drug operations in the region have focused on intercepting vessels, seizing narcotics shipments and arresting suspects rather than conducting lethal military attacks at sea.

The growing scrutiny comes as the Trump administration continues expanding military involvement in transnational security operations across Latin America and the Caribbean.

Mérida Sánchez, 66, is the first of 10 current or former Mexican officials indicted by U.S. prosecutors last month to appear before a court. Federal authorities accused him and others of protecting cartel operations and helping move large quantities of narcotics into the United States.

The former security official did not enter a plea during the hearing and was ordered detained pending further proceedings. Court records showed he is scheduled to return to court on June 1. A message seeking comment was left with his lawyer.

Prosecutors charged Mérida Sánchez with narcotics importation conspiracy, possession of machine guns and destructive devices, and conspiracy involving prohibited weapons offenses. If convicted, he faces a potential prison sentence ranging from 40 years to life.

The indictment also named Rubén Rocha Moya and Juan de Dios Gámez Mendívil among the accused officials. Both men announced temporary leaves of absence after the charges were unveiled but have not been taken into custody.

Mexico’s Security Cabinet said on social media that Mérida Sánchez crossed into the United States from Hermosillo, Sonora, on Monday and was detained by the U.S. Marshals Service at the Nogales border crossing in Arizona before being transferred to New York.Mérida Sánchez served as secretary of public security in Sinaloa from September 2023 until resigning in December 2024.

In that role, he oversaw the state police force and senior law enforcement appointments.According to the indictment, Mérida Sánchez received at least $100,000 in monthly cash payments from “Los Chapitos,” a faction of the Sinaloa Cartel led by sons of imprisoned cartel leader Joaquín ‘El Chapo’ Guzmán.

Prosecutors alleged the payments were made in exchange for targeting rival groups and leaking sensitive law enforcement information.Federal authorities said Mérida Sánchez warned cartel members about at least 10 planned raids on drug laboratories and safe houses during 2023, allowing operatives to remove drugs, weapons and personnel before authorities arrived.

Some of the accused officials are affiliated with Mexican President Claudia Sheinbaum’s Morena party. Following the indictments, Sheinbaum said Mexico would not shield any official proven to have committed crimes, but argued that any prosecution involving Mexican public officials should occur within Mexico’s judicial system.

Her remarks came amid heightened tensions with U.S. President Donald Trump, who has repeatedly threatened military action against drug cartels operating in Mexico.Mexico’s Foreign Ministry and Security Cabinet said they remain in institutional communication with U.S. authorities under existing bilateral cooperation frameworks.“El Chapo” Guzmán was convicted in the United States in 2019 and sentenced to life imprisonment.

Another senior cartel figure, Ismael ‘El Mayo’ Zambada, pleaded guilty last year to U.S. drug trafficking charges and is scheduled to be sentenced in July.

The cases involve Dawn Michelle Hunt, a 54-year-old former flight attendant and artist from the Chicago area, and Nelson Wells Jr., a 52-year-old Louisiana native and father of three, whose families say were unknowingly used as “blind mules” to transport narcotics hidden in luggage provided by other individuals.

The appeal places the cases at the intersection of humanitarian diplomacy and increasingly strained U.S.-China relations, as Washington and Beijing remain divided over trade, Taiwan and Iran-related tensions. For Trump, who has frequently highlighted efforts to secure the return of detained Americans abroad, the release of the two prisoners could offer a rare diplomatic breakthrough during a summit expected to yield limited concrete agreements.

Family members said they are attempting to deliver letters directly to Trump ahead of the meeting. Tim Hunt, Dawn Michelle Hunt’s brother, described his sister as highly intelligent and said she had been lured to China through what he characterized as a fraudulent “prize” trip.

According to her family, she was later given purses and a suitcase containing concealed narcotics that she unknowingly agreed to carry on an outbound flight.Wells’ family said he was detained after agreeing to transport another traveler’s suitcase while returning from a trip to China.

The individual allegedly disappeared after airport authorities discovered drugs hidden inside the bag.“I enjoyed serving my country,” Nelson Wells Sr., a U.S. Army veteran, said in remarks released through the family. “Now I just want my country to serve me.”A spokesperson for the U.S. State Department⁠ said Washington is providing consular assistance to both Americans and advocating for their health and welfare, while declining to comment further because of privacy considerations.

China’s foreign ministry said the two Americans were serving sentences for serious drug offenses and that Chinese authorities were handling the cases in accordance with the law while protecting their legitimate rights and health conditions.Advocates involved in the cases said U.S. officials have formally requested humanitarian releases from Chinese authorities, citing worsening medical conditions.

According to family members and advisers, Hunt requires blood transfusions and has declined surgery because of concerns over prison medical care, while Wells suffers from seizures, diabetes and high blood pressure.Beijing-based lawyer James Zimmerman, who is advising the families, said Chinese officials had privately indicated a willingness to consider humanitarian parole if the matter received higher-level political attention from Washington.

The cases follow a prisoner exchange in 2024 in which China and the United States each released three citizens that both governments said had been wrongfully detained after years of diplomatic negotiations.Peter Humphrey, a former prisoner in China who now advises families of foreign detainees, said U.S. embassy officials had increased engagement with Chinese authorities regarding the cases in recent months.

John Kamm, whose San Francisco-based Dui Hua Foundation researches political prisoners in China, said both Americans should be granted humanitarian parole because of their medical conditions. The foundation estimates that around 200 Americans are currently held in detention facilities across China.

The families said public attention to the cases intensified after testimony delivered at a September 2024 hearing of the Congressional-Executive Commission on China, where lawmakers examined the treatment of Americans imprisoned in China.Relatives are also backing legislation introduced by Representative Chris Smith that would expand support mechanisms for families of Americans detained overseas under disputed circumstances.

Tim Hunt said his father died in January before seeing his daughter released, while Wells’ family said his youngest daughter, now 12 and living in Japan, was only six months old when he was arrested.

United States Southern Command released video footage on social media showing what appeared to be a vessel at sea moments before an explosion engulfed it in flames.The military said it immediately alerted the United States Coast Guard to begin search-and-rescue operations for the surviving individual.The strike marked the latest in a series of U.S. military operations targeting suspected drug-trafficking boats in the eastern Pacific and Caribbean Sea since September

. According to Associated Press reporting, the campaign has resulted in at least 193 deaths. The Pentagon has repeatedly said the targeted vessels were operating along known drug-smuggling routes and linked to trafficking networks, though officials have not publicly presented evidence showing that the destroyed boats were carrying narcotics.

The operation came days after the White House announced that President Donald Trump had approved a revised U.S. counterterrorism strategy prioritizing the dismantling of drug cartels across Latin America and the Caribbean.

Trump has described cartels as an “unacceptable threat” to hemispheric security and has urged regional governments to intensify military cooperation with Washington against organized crime and transnational gangs.

The strikes have intensified in recent weeks despite growing scrutiny from legal scholars and human rights groups, who have questioned the legality of using military force against suspected traffickers outside conventional armed conflict zones.

Critics have argued the operations risk constituting extrajudicial killings because the U.S. government has disclosed limited evidence about the identities of those targeted or the intelligence underpinning the attacks.

The campaign has also coincided with a major expansion of U.S. military activity in Latin America and Caribbean waters, where the administration says it is attempting to curb narcotics flows into the United States and disrupt cartel financing networks.

Polling stations opened at 0700 local time (1200 GMT) for roughly 27 million eligible voters, as no candidate appeared close to securing the more than 50% required to win outright. The likely second-round vote on June 7 could extend uncertainty in the world’s third-largest copper producer amid rising crime and shifting geopolitical dynamics.

Voters expressed frustration with the political class. “Peru is a mess, and there’s no candidate worth voting for,” said Lima resident Gloria Padilla, reflecting widespread disillusionment after years of turmoil.

Since 2018, Peru has had eight presidents, a rapid turnover driven by impeachments, corruption scandals and fragile governing coalitions that have hindered policymaking.

Analysts say the instability has deepened distrust in Congress and other institutions.“People really despise the current Congress,” said Martin Cassinelli of the Atlantic Council, adding that many voters hold lawmakers responsible for prolonged political chaos.

The fragmented field reflects a broad anti-establishment mood, with candidates ranging from experienced political figures to outsiders. Conservative Keiko Fujimori, making her fourth presidential bid after reaching three prior runoffs, has campaigned on restoring order and economic stability, appealing to voters concerned about rising crime.

Her candidacy remains polarizing due to her political legacy and past legal challenges.Ricardo Belmont, a former Lima mayor running on a center-left platform, has surged into contention after a late rise in support, while comedian Carlos Alvarez has gained traction with a tough-on-crime message.

On the right, businessman and former mayor Rafael Lopez Aliaga has promoted socially conservative policies, though his support has fluctuated.Public security has dominated the campaign, with increasing homicide and extortion rates linked partly to drug trafficking and illegal mining.

Leading candidates have proposed expanding the military’s role in domestic security.The election also carries broader geopolitical implications. Peru’s economic ties with China, its largest trading partner and a major investor in mining and infrastructure, have drawn attention from the United States, which has increased engagement in the lead-up to the vote.

Whoever advances to the runoff will face a divided Congress and a newly reinstated Senate, complicating legislative efforts and potentially raising the risk of further political confrontation.

Polls are set to close at 5 p.m. local time (2200 GMT), with preliminary results expected shortly afterward.
