At least 13 militants were killed in Egyptian airstrikes in the restive Sinai Peninsula late Sunday, according to a local security source.
Apache helicopter gunships raided hideouts of alleged militants in southern Arish city in northern Sinai, the source said anonymously because he was unauthorized to speak to media.
The attack injured 10 other militants and destroyed a number of motorbikes and vehicles used by the militants, the source said.
Earlier Sunday, a roadside bomb killed a policeman and injured an army soldier in Arish.
