At least one soldier was killed and 18 others injured, some seriously, after an Israeli attack targeted an army centre in the town of Al-Amiriya in southern Lebanon, the Lebanese army said on Sunday.
The attack caused severe damage to the facility, the army added in a post on X.
The Israeli military did not immediately comment on the incident.
Lebanon's caretaker Prime Minister Najib Mikati said in a statement that Israel had sent "a direct and bloody message rejecting all efforts to reach a ceasefire, to bolster the Lebanese army's presence in the south, and to implement UN resolution 1701".
"This aggression is a matter for the international community, which is silent about what is happening to Lebanon," Mikati added in the statement.
UN Resolution 1701, adopted in 2006, ended a month-long war between Israel and Hezbollah by establishing a ceasefire and creating a buffer zone between the Litani River and the Israel-Lebanon border in a bid to promote long-term regional stability.
