'Significant Possibility' ISIS Downed Plane: U.K. Foreign Secretary

British Foreign Secretary Philip Hammond said this morning that there is a "significant possibility" that Islamic State (ISIS) militants brought down the Russian passenger jet last Saturday, which crashed in the Sinai peninsula while traveling between the sea resort of Sharm al-Sheikh and St. Petersburg, killing everyone on board.

Speaking to Sky News this morning, Hammond said: "ISIL-Sinai have claimed responsibility for bringing down the Russian aircraft, they did that straight away after the crash. We've looked at the whole information picture, including that claim, but of course lots of other bits of information as well, and concluded that there is a significant possibility."

The British prime minister has echoed the foreign secretary's comments, telling reporters this morning that it was "more likely than not" that the plane was downed by a terrorist bomb.

On Wednesday, a United States official told the Associated Press that early intelligence reports indicated a bomb caused the crash. Last night, Downing Street said the jet "may well have been brought down by an explosive device."

David Cameron is due to chair a second meeting of the government's emergency Cobra committee today to focus on how to help the 20,000 British people estimated to be in Sharm el-Sheikh at the moment. On Wednesday, Britain and Ireland suspended all flights to Sharm al-Sheikh. The Association of British Travel Agents estimates at least 9,000 of the British people in the resort town are holidaymakers, according to the BBC.

Egypt has dismissed claims by militants linked to the Islamic State that they brought down the plane while Russian experts say it is too early to reach a conclusion, according to the BBC.
