A Daesh leader in Egypt warned Muslims in the country to avoid Christian gatherings and government, military, and police establishments, saying the group plans additional attacks on these “legitimate targets,” Reuters reports. The news comes as security officials found the decapitated bodies of a father and his two sons in the northern Sinai border town of Rafah. The three men had been kidnapped by Daesh. The mother of the two siblings was reportedly killed by the group last week.
