Sharm el-Sheikh

A homemade explosive device brought down a Russian passenger plane over Egypt last month, the head of Russia’s FSB security service said Tuesday.

Flight KGL9268 was only 22 minutes into its journey when it disappeared from radar screens over the Sinai Peninsula, having apparently broken up in mid-air. But with a concrete explanation so far not forthcoming, what do we actually know?

The latest on the crash of a Russian plane in Egypt that killed all 224 people onboard.

The airport at Egypt’s resort of Sharm el-Sheikh has long had gaps in security, including a key baggage scanning device that often is not functioning and lax searches at an entry gate for food and fuel for the planes, security officials at the airport told The Associated Press.
