In a statement, the force reported: "A peacekeeper was tragically killed, and another seriously injured last night following a shell explosion at a UNIFIL site near Adchit al Qusayr."

UNIFIL urged "all parties to fulfill their obligations under international law and to ensure the safety and security of UN personnel and property at all times, including refraining from any actions that may endanger peacekeepers."

The force's spokesperson, Kandice Ardiel, had earlier informed Agence France-Presse that "a shell exploded at one of our sites in Adchit al Qusayr," noting that injuries occurred.

The war in the Middle East extended into Lebanon on March 2, after Hezbollah fired rockets into Israel in response to the assassination of Iran’s Supreme Leader Ali Khamenei on the first day of the American-Israeli attack.

Israel responded by launching extensive raids on Lebanon.

Hezbollah, in turn, reported engaging Israeli forces that have penetrated Lebanese territory and targeting them.

Since the latest war between Hezbollah and Israel began, UNIFIL has repeatedly reported its sites being hit by shells, most recently on March 23, when the force stated that its main headquarters in Naqoura was struck by a shell suspected to have been fired by a "non-state entity."
