The Islamic State group's affiliate in Egypt has released video purporting to show the beheading of eight Bedouin men it accused of working for the Egyptian and Israeli armies. The video, posted on the group's Twitter account late on Monday, also showed what it said were victims of Egyptian military operations in the restive Sinai Peninsula where an insurgency has killed scores of policemen and soldiers. The jihadist group, k**wn as Ansar Beit Al-Maqdis before pledging allegiance to the Islamic State group last **vember, has released footage in the past showing the execution of alleged informants. The men were first made to confess they worked for the armies of Egypt and Israel, which borders the Sinai and has been attacked by militants from the peninsula several times over the past three years.
