No U.S. plans to update flight advisory over Sinai -White House

WASHINGTON (Reuters) - The United States has no plans to update its flight advisory on Egypt's Sinai Peninsula, the White House said on Wednesday, after a Russian plane crash raised questions about possible extremist involvement. No U.S. airlines regularly operate out of Sinai and the Federal Aviation Administration has had a flight advisory for the area since March, White House spokesman Josh Earnest said. The FAA has advised civil aviation to avoid flying at lower altitudes - under 26,000 feet (7,900 meters) - over the Sinai, citing a potential risk associated with extremist activity, he said. "I'm not aware of any plans to update that specific advisory," Earnest said at a news briefing. Britain said on Wednesday it was delaying flights from the Sinai resort of Sharm el-Sheikh to Britain [nL8N12Z4UV] until it could assess security. Britain said the Russian plane that crashed on Saturday after taking off from Sharm el-Sheikh might have been brought down by an explosive device. All 224 people on board the Airbus A321 were killed.
