UK Investigators Think Bomb Brought Plane Down

British Prime Minister David Cameron declared Thursday it was “more likely than not” that a bomb brought down a Metrojet flight packed with Russian vacationers — a scenario that Russian and Egyptian officials dismissed as premature speculation.

The radical Islamic State group has claimed responsibility for bringing down the plane in the Sinai, a claim rejected by Russian and Egyptian officials as not credible. Egypt is, however, fighting an Islamic insurgency in the area where the plane crashed and Russia is supporting the Syrian government with airstrikes against ISIS targets. But there is still no official verdict, and we’ll have the latest on that front for you this morning.
