The Latest: UK warns of airport security overhaul

Britain's foreign secretary says airport security in many cities will need to be overhauled if it is confirmed the Russian plane crash in the Sinai was caused by a bomb planted by the Islamic State group or someone inspired by the militants.

U.S. and British officials suspect the Oct. 31 flight from Sharm el-Sheikh to St. Petersburg was brought down by a bomb on board, but Egypt warns it is too early to say what caused the crash.

The British government and U.S. officials have said intelligence suggests the plane was downed by a bomb, but Egypt says there's still no confirmation of what caused the crash.

Egyptian authorities are preventing camera crews from foreign media from filming inside the Sharm el-Sheikh airport, along the city's main tourist strip in Naama Bay, or other public areas.

Egyptian state and private channels, allowed to film inside the airport, highlighted security checks and luggage scanning at the main queue for international departures.
