BEIRUT — A video released by the Islamic State group purports to show the killing of a Palestinian man accused of being a spy for Israeli intelligence.

In the 13-minute video posted online Tuesday, a militant and a young boy dressed in camouflage stand behind a man dressed in an orange jumpsuit kneeling on the ground.

The militant says in French that the prisoner, identified as Mohamed Said Ismail Musalam, was sent by the Mossad to spy on the Islamic State. He then warns that ISIS fighters will soon "liberate Jerusalem."

The boy then steps in front of Musalam and shoots him in the head.

The Associated Press could not independently verify video, but it was released by the ISIS group's Furqan media arm and corresponds to previous ISIS videos.
