Indonesia’s Foreign Ministry said five Indonesian citizens were detained after Israeli forces boarded flotilla vessels approximately 250 nautical miles from Gaza’s coast, while four other Indonesians remained aboard two of the 10 boats still heading toward the territory. Malaysian Prime Minister Anwar Ibrahim said 16 Malaysians had also been detained during the operation.

The flotilla coalition, comprising more than 50 boats and nearly 500 participants from 45 countries, departed from Turkiye last week on what organizers described as the final leg of a mission to deliver humanitarian assistance to Gaza and protest Israel’s restrictions on aid access.

“The situation on the ground remains highly dynamic,” Indonesian Foreign Ministry spokesperson Yvonne Mewengkang said in a video statement, adding that Indonesian nationals still at sea remained vulnerable to interception by Israeli forces.

Indonesia urged Israel to release all detained activists and vessels and allow humanitarian aid to reach Palestinians “in accordance with international humanitarian law,” the ministry said.

Video footage circulating online showed Israeli naval personnel approaching several vessels in speedboats before boarding them in daylight on Monday. Organizers from the Global Sumud Flotilla said at least 41 boats had been intercepted and 337 participants detained.

Anwar said Malaysia was coordinating with other governments to secure the activists’ release. In a statement posted on social media, he said the interception violated international law and obstructed humanitarian relief efforts for Gaza’s civilian population.

Israeli authorities have not publicly detailed the status of those detained. Activists from several Asian countries, including South Korea, Sri Lanka and Vietnam, were also reported to be among those taken into custody.

Indonesian Foreign Minister Sugiono joined counterparts from Turkiye, Bangladesh, Brazil, Colombia, Jordan, Libya, the Maldives, Pakistan and Spain in issuing a joint statement condemning attacks on civilian vessels and what they described as arbitrary detentions of humanitarian activists.

The ministers said such actions constituted violations of international law and called for the immediate release of all detainees while urging respect for the activists’ rights and safety.

The latest interception follows similar incidents in recent months involving aid flotillas attempting to reach Gaza. Last month, Israeli forces intercepted more than 20 boats near the Greek island of Crete and detained roughly 175 activists, according to organizers.
Humanitarian conditions in Gaza have continued to deteriorate amid ongoing Israeli military operations following the outbreak of the war in October 2023.

The United Nations has said approximately 1.8 million people in Gaza have been displaced and remain heavily dependent on humanitarian assistance amid mounting shortages of food, medicine and shelter.

Spanish Foreign Minister Jose Manuel Albares said the Israeli charge d’affaires was called in to receive Madrid’s protest over what he described as the “unacceptable and intolerable” extension of the detention of Saif Abu Keshek, a Spanish citizen of Palestinian origin detained after Israeli forces intercepted the Global Sumud Flotilla in international waters near Greece last week.

An Israeli court has extended the detention of Abu Keshek and Brazilian activist Thiago Avila until Sunday, despite calls from international rights groups and foreign governments for their release. Israeli authorities have not filed formal charges against either activist.

The flotilla was the second maritime initiative in the past year aimed at challenging Israel’s blockade on Gaza, where shortages of food, medicine, water and fuel have intensified during the war between Israel and the Palestinian militant group Hamas.

Israeli forces intercepted the vessel and deported several activists to Europe while detaining Abu Keshek and Avila. Rights organizations have alleged the detainees were subjected to abuse while in custody, accusations Israeli authorities have denied.

The latest dispute underscores the widening rupture in relations between Spain and Israel since the outbreak of the Gaza conflict following Hamas’ Oct. 7, 2023 attack on Israel. Spanish Prime Minister Pedro Sanchez has repeatedly criticized Israel’s military campaign in Gaza and previously described it as a “genocide,” a characterization Israel strongly rejects.

Diplomatic ties deteriorated further after Spain formally recognized a Palestinian state in 2024, prompting Israel to recall its ambassador from Madrid. Spain later dismissed its own ambassador to Tel Aviv in March.

The diplomatic clash coincided with Madrid’s decision to honor Francesca Albanese, the United Nations special rapporteur on human rights in the occupied Palestinian territories, with the Order of Civil Merit.

Sanchez’s office said Albanese was recognized for her work documenting alleged violations of international law in Gaza. Albanese has repeatedly accused Israel of committing genocide during the conflict, allegations Israel denies, accusing critics of antisemitism.

The United States has imposed sanctions on Albanese, accusing her of “biased and malicious” criticism of both Washington and Israel. Spain has urged the European Commission to prevent the U.S. sanctions from being enforced within the European Union.

France and Germany have also criticized Albanese and called for her resignation over remarks referring to a “common enemy of humanity,” although Albanese has denied that the statement was directed at Israel.

Spanish national Saif Abu Keshek and Brazilian national Thiago Avila appeared before a court in Ashkelon for a second hearing, after being brought to Israel last week following the interception of their vessel by Israeli forces off the coast of Greece.“The court approved their detention until Sunday morning,” said Miriam Azem of Adalah, which is providing legal representation.

An AFP journalist witnessed the activists being escorted into the courtroom with their legs shackled.The two were among dozens of individuals aboard a flotilla that had set sail from France, Spain and Italy with the stated aim of delivering humanitarian supplies to Gaza and challenging Israel’s long-standing blockade.

Adalah said the activists have been on a hunger strike for six days and alleged that both were subjected to physical and psychological abuse in detention. The group said they were being held in isolation under constant high-intensity lighting, with Avila allegedly exposed to extremely cold temperatures.“They are kept blindfolded at all times whenever they are moved outside their cells, including during medical examinations,” the group said.

Israeli authorities have rejected the allegations.During an earlier hearing, prosecutors presented a list of charges including assisting the enemy during wartime and membership in, and providing services to, a terrorist organization, according to Adalah.

Defense lawyers challenged Israel’s jurisdiction, arguing the activists had been unlawfully detained in international waters.Israel’s foreign ministry said both individuals were affiliated with the Popular Conference for Palestinians Abroad, which it alleged has links to Hamas. It described Abu Keshek as a leading member and said Avila was also suspected of involvement in illegal activity.

The flotilla was part of the Global Sumud initiative, whose previous attempt last year was similarly intercepted. Israeli forces stopped the latest convoy early on Thursday off Greece’s coast.Israel has maintained a blockade on Gaza since 2007 and controls access points into the territory.

Aid flows have been severely disrupted during the ongoing war that began in October 2023, contributing to shortages of essential supplies.
