Obama first commented on the catastrophe of the Russian airliner

US President Barack Obama admitted the likelihood that a Russian plane crashed last week in Egypt was destroyed in an explosion.

During the collapse of the liner, all 224 people on board were killed.

“We will spend a lot of time to ensure that our own investigators and our intelligence community will establish the reason before making any decisive statements,” Obama said in an interview with Seattle’s KIRO radio station on Thursday. “However, there is definitely a chance that there was a bomb on board.”

British Prime Minister David Cameron also considers it “more likely” that the plane crashed as a result of the explosion.

Cameron on Thursday met in London with Egyptian President Abdel Fattah al-Sissi, who, like the Russian side, considers the version of the bomb on board the plane to be no more than speculation.

“We cannot be sure that the Russian airliner crashed as a result of the terrorist act, but this seems to be more and more likely,” said the British prime minister.

Previously "Forum" reportedthat the plane of the Russian company Metrojet flew from Sharm el-Sheikh to St. Petersburg and crashed over the Sinai Peninsula.

Responsibility for liner crash took the Islamic State grouping itself, however, it did not provide any evidence of its involvement.

US officials say the conversations they intercepted indicate that extremists were involved, and that someone from Sharm el-Sheikh airport helped to place the bomb on the plane.

Al-Sissi denied the statement of the "Islamic State", calling it propaganda aimed at undermining the stability and security of Egypt.

Egyptian authorities soon after crash statedthat the cause of the crash could be a technical failure.

The company Metrojet, in turn, rejected the version of the technical fault, saidthat the only reasonable explanation for what happened can only be an “external impact”.
