Egypt's state news agency says three policemen have been killed in a roadside bombing in the turbulent north of the Sinai Peninsula.

MENA quoted an unidentified security official saying that the Wednesday explosion targeted an armored personnel carrier in the city of el-Arish, wounding another 8 policemen.

The official says the wounded were taken to the military hospital in el-Arish.

There was no immediate claim of responsibility for the latest attack. A local affiliate of the Islamic State group has claimed responsibility for a series of attacks on security forces in Sinai since 2014.

Egypt has for years been fighting a Sinai-based Islamic insurgency. The attacks have grown more frequent and deadlier since 2013, when President Abdel-Fattah el-Sissi, then the defense minister, led the ouster of Islamist President Mohammed Morsi.
