Who were the Hamas officials killed in Beirut?

Other significant Hamas officials died in Tuesday's drone strike that killed senior leader Saleh al-Arouri, harming the armed group's military capabilities in Lebanon during Israel's war on Gaza. According to Lebanese state media, the strike on a Hamas office in the Hezbollah stronghold of Dahiyeb, a southern suburb of Beirut, killed seven people. Hamas described the killing of al-Arouri on its official TV channel as "a "cowardly assassination" by Israel. Israeli Prime Minister Benjamin Netanyahu's adviser Mark Regev told the United States-based TV news channel MSNBC that Israel had not taken responsibility for the attack and added: "Whoever did it, it must be clear that this was not an attack on the Lebanese state." Al-Arouri, 57, was the deputy chief of the Hamas political bureau.
