“According to our specialists’ assessment, a homemade explosive device with an equivalent of 1 kilogram of TNT on board the aircraft exploded, which lead to the plane 'breaking up' in midair, which would explain the scattering of the plane’s fuselage across a wide area,” Bortnikov said during a meeting.
Russian Special Forces have determined the A321 passenger jet that crashed over Egypt’s Sinai Peninsula on October 31 killing all 224 on board was a terrorist act.
“We can definitely say this was a terrorist act,” Russian Federal Security Service head Alexander Bortnikov said during a meeting with Russian President Vladimir Putin, Russia-based Sputnik News reported Tuesday.
An investigation into A321 crash shows traces of an explosive material in personal items and parts of the plane, Bortnikov added.
He also said that Russia offers $50mln for the information on those who might have been involved in the terrorist attack on the A321.
