Hamas said that one of its senior leaders, Saleh Al-Arouri has been killed in an attack in the south of the Lebanese capital Beirut.
This has raised fears of a potential escalation in fighting in the region.
According to the BBC, Saleh Al-Arouri, deputy head of the political bureau of Hamas, was “martyred in a treacherous Zionist airstrike in Beirut.”
Arouri was considered one of the founding members of the group’s military wing, the Izz ad-Din al-Qassam Brigades, and was based in Beirut.
Two other leaders from Hamas’ military wing, Samir Findi Abu Amer and Azzam Al-Aqraa Abu Ammar, were also among those killed in the strike, according to Hamas officials.
At least four people were killed in the attack that targeted an office belonging to Hamas in the southern Beirut suburb of Dahieh.
The area is also a stronghold of Iran-backed Hezbollah.
The Israel Defense Forces (IDF) declined to comment when asked about the announcement and its spokesperson Daniel Hagari skirted a question from a reporter on Tuesday about the matter saying “we are focused on fighting against Hamas.”
But in a seemingly veiled reference to the killing, Israel’s far right Finance Minister Bezalel Smotrich wrote on his official social media platforms that all of Israel’s enemies will “perish.”
