The UN peacekeeping mission in Lebanon (UNIFIL) said a peacekeeper was killed when a projectile exploded at one of its positions near the southern Lebanese ​village of Adchit Al Qusayr on Sunday. Another peacekeeper was critically injured, it said in a ‌statement early on Monday.

Indonesia’s foreign ministry said on Monday the deceased peacekeeper was one of its citizens and that three others were injured by “indirect artillery fire” in the vicinity of the Indonesian UNIFIL contingent’s position near Adchit Al Qusayr.

“We do not know the origin of the projectile. We have launched an investigation ​to determine all of the circumstances,” UNIFIL said.

UN Secretary-General Antonio Guterres strongly ⁠condemned the incident, saying attacks on peacekeepers are grave violations of international humanitarian law and may ​amount to war crimes.

He called for accountability and urged all parties to ensure the safety ​of UN personnel.

UNIFIL is stationed in southern Lebanon to monitor hostilities along the demarcation line with Israel — an area that is at the heart of clashes between Israeli troops and Hezbollah fighters.

The mission, which will be halted ​at the end of 2026, has been sporadically caught in the crosshairs of both Israel and ​Hezbollah over the last couple of years.

On March 6, Ghana’s armed forces said the headquarters of its UN peacekeeping battalion ⁠in Lebanon was hit by missile attacks, leaving two soldiers critically injured.

Israel’s military later acknowledged that its tank fire had hit a UN position in southern Lebanon that day, wounding the Ghanaian peacekeepers.

The military said its troops had responded to anti-tank missile fire from Hezbollah, which had moderately wounded ​two of its soldiers.

“Once ​again, we call on ⁠all actors to uphold their obligations under international law and to ensure the safety and security of UN personnel and property at all times, ​including by refraining from actions that may put peacekeepers in danger,” UNIFIL ​said.

Indonesia condemned ⁠the incident and said any harm to peacekeepers is unacceptable, while reiterating its condemnation “of Israel’s attacks in Southern Lebanon.”
