Lebanese group Hezbollah said on Sunday that it destroyed an Israeli military vehicle, in an attack along the border between Lebanon and Israel.
In a statement, the group said "those inside the Israeli vehicle were killed and wounded" in the operation, without giving further details.
The Israeli army, meanwhile, said anti-tank missiles were fired from Lebanon, which hit military positions in northern Israel.
"We returned the fire toward the source of the attack in southern Lebanon," a military statement said.
The escalation came a week after an Israeli drone fell and another exploded over the southern suburb of Beirut.
In 2006, Israel launched a war against the Hezbollah, during which at least 1,200 people, mostly Lebanese civilians, were killed.
