At least 150 people are dead following an explosion Friday that hit a mosque on the al-Rawdah mosque in the town of Bir al-Abd, 40 km (25 miles) from the North Sinai provincial capital of El-Arish, Egyptian state news agencyMena reported.
Four off-road vehicles reportedly bombed the mosque and fired on the worshipers during a sermon at around noontime.
The well planned attack and included bombs and shooting.
Witnesses watched terrorists enter the mosque in order to kill as many worshipers as possible. The attack occurred during Friday prayers to maximize the numbers of Muslim worshipers.
The terrorists, after initiating the attack on Friday around noon local time, apparently tried to stop emergency services from reaching the mosque.
“They were shooting at people as they left the mosque,” a resident told Reuters. “They were shooting at the ambulances too.”
No group has claimed responsibility, although it appears to have been perpetrated by the local Islamic State (ISIS) affiliate.
Egyptian President Abdel Fattah al-Sisi has declared a state of emergency.
