Sinai plane was brought down by terrorists, says Russian security chief

The director of the Federal Security Service of the Russian Federation, Alexander Vasilyevich Bortnikov, has told President Vladimir Putin that terrorists were responsible for the Russian plane that was blown up in Egypt last month.

Bortnikov said that the plane crash was an act of terror and traces of explosives have been discovered in the plane wreckage.

"During the flight, a homemade device with the power of 1.5 kilograms of TNT was detonated. As a result, the plane fell apart in the air, which can be explained by the huge scattering of the fuselage parts of the plane," he told Putin, according to a Russia Times report.

Putin has reportedly vowed to find the attackers and punish them for the act.

On 31 October, 224 people were killed on board the Russian Airbus, Kogalymavia Flight 9268, after it crashed over the Sinai Peninsula in Egypt.
