CAIRO A bomb exploded at a police station in a province north of Cairo early on Wednesday, wounding 12 people, the Interior Ministry said in a statement.
Unknown assailants threw the bomb from a passing car in Mansoura, the capital of Dakhalia province, two security sources told Reuters. The security sources said five police officers were hurt; the ministry said 12 people were injured.
The explosion occurred after a day of clashes between opponents and Islamist supporters of Egypt's deposed president, Mohamed Mursi, killed nine people in Cairo.
The Muslim Brotherhood accuses the army of orchestrating a coup that has exposed deep political divisions in the Arab world's most populous and influential nation.
