The leader of Islamic State in Sinai responsible for the death of 305 Egyptians in a 2017 mosque massacre has been killed in fighting with the Egyptian Armed Forces, the Sinai United Tribes announced on Monday.

Hamza Adel Muhammad Al-Zamili, better known by the Jihadi moniker Abu Kazem Al-Maqdisi, was killed in combat along with nine other Islamic State fighters. Three others were arrested, and as of Tuesday, Egyptian military operations were still underway, according to the Sinai United Tribes, which is aligned with the Egyptian government. 

Rawdah mosque massacre

In 2017, 305 people at Al Rawdah mosque in the northern Sinai were killed in a bombing and gun attack during Friday prayers. Many of those killed were reportedly Sufis, a branch of Islam that is considered idolatrous by the Islamic State. Maqdisi was reportedly responsible for the attack.

"The armed forces and the police will avenge our martyrs and restore security and stability with the utmost force," Egypt's President Abdel Fattah al-Sisi said in a televised address at the time. "What is happening is an attempt to stop us from our efforts in the fight against terrorism, to destroy our efforts to stop the terrible criminal plan that aims to destroy what is left of our region."

A Gazan extremist

Maqdisi was from Gaza but was at odds with the ruling Hamas regime. He had accused Hamas of cooperating with Israel and Egypt to crack down on ISIS-affiliated radicals, Voice of America reported.

The Islamic State in Sinai pledged allegiance to IS in 2014 and has continued to conduct terrorist attacks in the Egyptian territory since the decline of the parent group.
