Lebanon’s militant Hezbollah group fired anti-tank missiles and artillery shells at an Israeli military convoy in a disputed area along the border, killing an Israeli civilian, the group and Israel’s military said Friday.

Hezbollah said that its fighters ambushed the convoy shortly before midnight Thursday, destroying two vehicles. The Israeli military said the ambush wounded an Israeli civilian doing infrastructure work, and that he later died of his wounds.

Low-intensity fighting along the Israel-Lebanon border has repeatedly threatened to boil over as Israel has targeted senior Hezbollah militants in recent months.

Tens of thousands of people have been displaced on both sides of the border. On the Israeli side, the cross-border fighting has killed 10 civilians and 12 soldiers, while in Lebanon, more than 350 people have been killed, including 50 civilians and 271 Hezbollah members.
