The head of Egypt’s Sharm el-Sheikh airport has been replaced amid growing international concern that the Russian plane which crashed after departing from the airport was downed by a bomb.

Adel Mahgoub, chairman of the state company that runs Egypt’s civilian airports, says airport chief Abdel-Wahab Ali has been “promoted” to become his assistant. He said the move late Wednesday had nothing to do with media skepticism surrounding the airport’s security, according to radio.ksl.com.

Mahgoub said Ali is being replaced by Emad el-Balasi, a pilot.

All 224 aboard the plane were killed in the Saturday morning crash. U.S. and British officials earlier Wednesday said they suspect the plane may have been brought down by a bomb and Britain said it was suspending flights to and from the Sinai Peninsula as a precaution.
