The victims included two senior officers from the investigation bureau of the Sheikh Zuweid police station and two soldiers. Among the civilian casualties is a six years old child.

The Islamic State militant group issued a statement on accounts of its alleged followers claiming the attack.
In March, the Egyptian military, as part of the Sinai 2018 operation, said it killed 46 “extremely dangerous” suspected terrorists during a fire exchange in North and central Sinai.
In February in Cairo, a suicide bomber directly blew himself up when security personnel came close to arrest him at the area of Al-Darb al-Ahmar near Al-Azhar Mosque, which is regularly crowded with people and vendors. Three policemen were killed.
