Ansar Beit al-Maqdis, which now calls itself the Sinai Province, said on its 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 ID cards said he worked for Texas-based energy company Apache Corp. and Qarun Petroleum Co., a joint venture with Egypt.
