Leaders: Bomb may have downed plane

Obama, Cameron go public with suspicions, but Russia reserves judgment while probe continues

US President Barack Obama and British Prime Minister David Cameron both believe a bomb may have downed a Russian plane in Egypt, with reports on Friday suggesting their view was based on intercepted communications between militants.

But Moscow, which launched airstrikes against Islamist fighters that included Islamic State in Syria more than a month ago, said it was premature to reach conclusions that the flight was attacked.
