US Secretary of State John Kerry informed his Egyptian counterpart Sameh Shokry that the US didn’t officially issue a statement regarding the Russian plane which crashed over Egypt's Sinai on Saturday, Egypt's foreign ministry said in a statement on Thursday.

“Kerry told Shoukry that what is reported by some media outlets over American observations of the reason of the incident doesn’t represent the stance of the US administration,” the statement read.

On Thursday, the CNN news network quoted a US intelligence official saying that the Russian plane, Air Bus A-321, was brought down by a bomb.

Last Saturday, a Russian plane heading from Egypt’s Sharm El-Sheikh to Russia’s St. Petersburg crashed over the Sinai Peninsula, killing all 224 people on board.

Egypt has opened an investigation into the causes of the crash, allowing Russia to take part.

An aviation team of Egyptian and Russian experts retrieved the black boxes of the plane in order to determine the reason behind the crash of the Airbus A-321.

The British government decided to suspend its flights over Sinai on Wednesday pending further assessment of safety procedures at Sharm El-Sheikh’s airport.

"While the investigation is still ongoing we cannot say categorically why the Russian jet crashed, but as more information has come to light we have become concerned that the plane may well have been brought down by an explosive device," the British government said in a statement.
