In a statement, Hamas mourned on Monday Fatah Sharif Abu Al-Amine, the leader of Hamas in Lebanon and member of the movement's leadership abroad who was killed along with his wife, son, and daughter, in an Israeli airstrike on his home in the El Buss refugee camp in Tyre, south Lebanon. 

The group pledged in its statement "to remain steadfast on its path, until the Israeli occupation is defeated and expelled from the land of Palestine and Al-Quds and the detainees are liberated."

The strike on El Buss, one of 12 Palestinian refugee camps in south Lebanon, was the first time the camp had been targeted since the start of the recent Israeli airstrikes on Tyre and elsewhere in the country that killed more than 800 and wounded hundreds of others.

More assassinations
 

Hamas's statement came hours after the Popular Front for the Liberation of Palestine (PFLP) said three of its leaders were killed in an Israeli attack on Beirut's Cola district early on Monday, in what would be the first time Israel’s military had struck the centre of Lebanon’s capital since 2006.

The group said in a statement that its military security chief Mohammad Abdel-Aal, military commander Imad Odeh, and Abdelrahman Abdel-Aal were killed.

Moreover, a security source told AFP that Monday's drone attack targeted a flat belonging to Jamaa Islamiya in central Beirut.

The Israeli assassinations of Palestinian leaders in Lebanon on Monday come amid an intense Israeli campaign of targeted assassinations against Hezbollah leaders in the country in the past several days.

On Thursday, Israel killed Hezbollah leader Hassan Nasrallah in an airstrike on south Beirut after assassinating a number of top Hezbollah commanders in recent weeks.

​An Israeli strike in January killed Hamas deputy leader Saleh Al-Aruri in south Beirut.

In August, another Israeli strike on a vehicle in the south Lebanon city of Sidon killed Hamas commander Samer Al-Hajj.
