An Israeli drone strike on the Lebanese capital killed a top commander from militant group Jama'a Islamiya.
The group said this in a statement on Tuesday, while there was no immediate comment from the Israeli military.
The statement said the strike on Tuesday morning killed Hussein Atawi, a leading commander in the armed branch of the Sunni Islamist Jama'a Islamiya known as the Fajr Forces, as he was driving from his home to his office in Beirut.
The Fajr Forces reportedly fired rockets across Lebanon's southern border at Israel throughout the year-long war that ended last year in a ceasefire deal.
Israeli airstrikes are said to have killed several of the group's members during the conflict.
Since the ceasefire, Israel has continued to carry out strikes on Lebanese territory, mostly targeting fighters from Lebanese armed group Hezbollah or its arms depots.
Israeli troops also still occupy five hilltop positions in southern Lebanon.
Meanwhile, Lebanon, Hezbollah and the Jama'a Islamiya have condemned the strikes and Israeli troop presence, calling them violations of the truce and of Lebanon's sovereignty.
Israel said the fighters and weapons pose a threat to Israeli civilians.
