Three loud blasts were heard in the Iraqi capital, according to an AFP reporter on the ground. A security source said the artillery fire was ceremonial and intended to mark the establishment of the new administration.

The celebratory firing came days after Iraq finalized the formation of a new government following extended political negotiations among rival factions.

Earlier on Friday, Antonio Guterres welcomed the creation of the new Iraqi government and reaffirmed the United Nations’ commitment to supporting the country’s economic and social development efforts.

The formation of the cabinet under Al-Zaidi is viewed as a key step in efforts to stabilize Iraq’s political landscape amid continuing economic challenges, regional tensions and security concerns.

UNIFIL said the blast occurred on Sunday and that it had launched an investigation to determine the origin of the projectile. “We do not know the origin of the projectile,” the mission said, adding that emergency response teams were deployed.

Indonesia’s foreign ministry confirmed the fatality involved one of its nationals and said three other Indonesian peacekeepers were injured by indirect artillery fire near their position.

Jakarta condemned the incident, calling any harm to peacekeepers unacceptable, and reiterated its criticism of Israeli military actions in southern Lebanon.

Rising risks for UN forcesUNIFIL operates in southern Lebanon to monitor hostilities along the demarcation line with Israel, where clashes between Israeli forces and Iran-backed Hezbollah fighters have intensified in recent weeks.

The mission has increasingly been caught in crossfire. Earlier this month, Ghana said two of its peacekeepers were critically injured after a UN position was struck. Israel later acknowledged its tank fire had hit the site while responding to anti-tank missiles from Hezbollah.

The escalation follows Hezbollah rocket fire into Israel on March 2, which triggered a new Israeli offensive in southern Lebanon amid a wider regional conflict involving Iran.

UNIFIL urged all parties to adhere to international law and avoid actions that endanger UN personnel and facilities.
