Israeli Prime Minister Benjamin Netanyahu had already threatened to kill al-Arouri, the organization's leader in the West Bank, before Hamas's bloody attack on October 7th. After tonight's attack, Israeli officials vowed that all Hamas leaders were “sentenced to death.”

Hamas condemned the killing as a “cowardly assassination” by Israel and said such attacks “will not result in breaking the will and fortitude of our people or undermining the continuation of their brave resistance.”

Lebanon's National News Agency (NNA) reported that “four people were martyred and several others were injured when the Hamas office was attacked.” The building is located in Dahiyeh, an area in Beirut's southern suburbs and a stronghold of the Iranian-backed Hezbollah.

Hezbollah leader Sayyed Hassan Nasrallah, for his part, promised retaliation against any Israeli attacks on Palestinian officials in Lebanon.

Hamas added that two Qassam Brigade commanders were also killed in the explosion.

Israeli Prime Minister Benjamin Netanyahu said at a news conference in November that he had “ordered the Mossad to take action against the leaders of Hamas wherever they are” after the terror group killed 1,200 people, mostly civilians, in its Oct. 7 incursion had.

al-Arouri, 57, was deputy head of Hamas' political bureau and was considered the de facto leader of the organization's military wing.

He is believed to have planned and participated in the 2014 kidnapping and subsequent murder of three Israeli teenagers Gil-ad Shaar, Eyal Yifrach and Naftali Fraenkel, as well as several other attacks.

The political leader was behind bars several times in Israel and was released in March 2010 as part of efforts to secure a broader prisoner swap in exchange for Gilad Shalit, an IDF sergeant kidnapped by Hamas in 2006.

Al-Arouri was later involved in a deal in which more than 1,000 Palestinian prisoners were released in exchange for the sergeant.

Lebanese media reported that, according to Islamic Jihad sources, the movement's secretary general, Ziyad al-Nakhala, was not injured in the attack.

The explosion in Beirut came after more than two months of intense gunfire between Israeli troops and Hezbollah members along Lebanon's southern border.

Since the fighting began the day after Black Saturday, the conflict has been concentrated just a few kilometers from the border, but the Israeli Air Force has repeatedly attacked Hezbollah targets deeper in Lebanon.

Earlier in the day, Hezbollah said its fighters had carried out several attacks on Israeli military posts along the Lebanese-Israeli border.

The blast came during more than two months of intense exchanges of fire between Israeli troops and members of Hezbollah along Lebanon's southern border

Clashes on the Israel-Lebanon border have already displaced tens of thousands of people, despite Israel previously claiming it did not want to go to war with its neighbor.

But just last month, Benny Gantz, a senior member of Benjamin Netanyahu's war cabinet, said the situation on Israel's border with Lebanon “must change,” hinting at an escalation with Hezbollah.

In November, Israel's Defense Minister Yoav Gallant said, referring to Hezbollah Secretary General Hassan Nasrallah: “When you hear that we attacked Beirut, you will understand that Nasrallah has crossed this line.”
