Four civilians were killed in North Sinai's El-Arish after an improvised explosive device planted in a garbage bag detonated late Friday in the vicinity of a police station, state owned MENA agency reported.
According to a security source, the IED exploded on El-Bahr Street as a sanitation truck was collecting garbage, killing a cleaning worker and a passerby.
Two members of the same family were also killed in the blast, 21-year-old Basma Said Mostafa Rashad, who died of her injuries on Saturday, and her brother Mohamed Said Mostafa, who died instantly when caught in the blast.
Three other people were injured in the explosion.
No group has yet claimed responsibility for the attack, which comes only one day after Egypt's army announced that it killed the leader of Egypt’s Islamic State affiliate Ansar Beit Al-Maqdis in airstrikes south of El-Arish.
The group, which originated in Sinai and pledged allegiance to the Islamic State militant group in November, has claimed responsibility for most of the attacks against security personnel and installations in the restive governorate.
