Egyptian authorities say a bomb is the most plausible reason for last weekend’s deadly Russian jet crash after takeoff from Egypt’s Sharm el Sheikh Airport, as Russia decides to halt all flights to Egypt.

A government official in Sharm el Sheikh told ABC News Egyptian authorities can no longer dismiss the possibility that a bomb was placed on the plane and, in their mind, it is the most plausible scenario, adding that a technical problem is now at the bottom of their list of possible scenarios.

Meanwhile, Russian President Vladimir Putin today agreed to suspend all Russian flights to Egypt, a Putin spokesman confirmed, according to Interfax.

The Russian news agency also quoted a Russian official’s suggestion that all Russian flights to Egypt, the plane’s origin, should be stopped until the cause of the plane crash is determined.

“While we are still have not determined the true causes of what happened, I think it would be advisable to halt all flights by Russian aviation to Egypt. That is, above all, tourist flights,” Aleksandr Bortnikov, director of the Federal Security Service of the Russian Federation, said, according to Interfax.
