At least eight policemen and civilians were wounded on Monday when explosions hit two houses in Egypt's El-Arish, the provincial capital of the North Sinai region, security and medical sources said.
Militants planted two bombs in two adjacent houses, both inhabited by police, the sources said. The force of the explosions led to the collapse of large parts of the homes, injuring three policemen and five civilians.
The extent of their injuries was not immediately clear.
Egypt is facing a Sinai-based insurgency that has killed hundreds of policemen and soldiers since the army toppled Islamist President Mohamed Morsi after mass protests against his rule in 2013.
The most active militant group is Sinai Province, which has pledged allegiance to Islamic State, the Sunni group that controls large parts of Iraq and Syria.
Egypt executed six members of Sinai Province for carrying out an attack on soldiers near Cairo last year, their lawyer said in May.
