Extremist group the Islamic State has claimed responsibility for an attack that claimed the lives of at least 13 policemen in Egypt’s Sinai Peninsula, according to a BBC report. Government forces killed five of the militants who carried out the attack, officials said.

A mortar attack hit a checkpoint in El-Arish, officials said, but ISIS claimed a suicide bomber blew up a car with explosives at the checkpoint.

On Twitter, ISIS claimed that the attack was "part of a series of operations in response to the humiliation and searching of Muslim women at checkpoints."

The extremist group might have also been responsible for a terrorist attack in Istanbul Friday, which left five people, including two American citizens, dead.
