On Tuesday, an explosion in Beirut killed Saleh al-Arouri, a top official with Hamas, and three others, according to officials from Hamas and Hezbollah.
Lebanon’s National News Agency attributed the blast to an Israeli drone, but Israeli officials haven’t commented. If Israel is responsible, it could escalate tensions in the Middle East.
Hezbollah’s leader vowed retaliation against any Israeli targeting of Palestinian officials in Lebanon.
Lebanon’s Prime Minister called it a “crime” aiming to provoke confrontation with Israel.
Al-Arouri, a Hamas founder, was threatened by Israel’s Prime Minister even before the recent conflict.
The explosion occurred amid ongoing clashes between Israeli troops and Hezbollah along Lebanon’s border.
