A terror attack could be the reason for the EgyptAir crash, Aleksandr Bortnikov, head of Russia’s Federal Security Service (FSB), has said.
"Unfortunately, today there was another incident with an Egyptian Airlines plane. Apparently, it is a terrorist attack, which killed 66 people from 12 countries,” Bortnikov was cited as saying by TASS.
The FSB chief urged "all concerned parties, including our partners in Europe, to undertake joint measures to identify the persons involved in this heinous act."
Egypt’s Aviation Minister Sherif Fathy has told journalists that the missing plane is more likely to have been brought down by a terrorist attack than a technical failure.
“If you analyze the situation properly the possibility of having a terror attack is higher than the possibility of having a technical [problem]," he said.
