Israel's military said it was investigating whether its own fire killed an Israeli civilian near the Lebanese border on Sunday, after Hezbollah claimed an attack in the same area. Israeli emergency workers said earlier Sunday that a man was killed in a "direct hit" on his car by a rocket from Lebanon.
Lebanon's Iran-backed Hezbollah militant group said after the incident that its fighters had attacked Israeli soldiers in the same area.
But the Israeli army later announced it was "conducting a comprehensive investigation" into the death.
"The possibility that the incident involved fire originating from IDF soldiers is being examined," the military said in a statement.
Lebanon was pulled into the Middle East war when Hezbollah began firing rockets into Israel on March 2 to avenge the killing of Iran's supreme leader Ali Khamenei in Israeli-US attacks.
Israel has sent troops into Lebanon and carried out extensive airstrikes in the country, while Hezbollah continues to fire rocket barrages across the border.
