CAIRO (AP) — An Egyptian militant organization which pledged allegiance to the Islamic State group has claimed responsibility for the killing of an American oil worker.
Ansar Beit al-Maqdis, which now refers to itself as the Sinai Province, said on its official Twitter account late Sunday that it killed William Henderson. It published pictures of his passport and two identification cards. It did not say when or how it killed him.
The passport said he was a 58-year-old from Texas and his identification cards said he worked for Texas-based energy company Apache Corp. and Qarun Petroleum Co.
Apache said in August that one of its supervisors had been killed in an apparent carjacking in Egypt's Western Desert. The company did not identify the man. It could not immediately be reached for comment.
