Al Arish: Four Egyptian policemen were on Monday wounded by a bomb in the Sinai Peninsula, security sources said.
The device was planted at the entrance to an apartment building in the provincial capital of Al Arish.
Egypt, the most populous Arab country, faces an Islamist militant insurgency that has killed hundreds of soldiers and policemen since the army toppled president Mohammad Mursi of the Muslim Brotherhood in 2013 after mass protests against his rule.
Most of the violence has been in the Sinai, which shares a fronter with the Gaza Strip and the Israeli regime. But some attacks have occurred in cities and towns.
In a separate attack on Monday in Cairo, a bomb exploded in the car of a police officer who was not in the vehicle at the time, security sources said.
Security officials say Sinai-based militants are inspired by Daesh, the Al Qaida offshoot that controls parts of Iraq and Syria and wants to redraw the map of the Middle East.
