Russian airliner crash: Focus on 'technical problems'
A Russian airliner has crashed in central Sinai killing all 224 people on board, Egyptian officials have said.
The Airbus A-321 had just left the Red Sea resort of Sharm el-Sheikh, bound for the Russian city of St Petersburg.
Wreckage was found in the Hasana area and bodies removed, along with the plane's "black box".
