Egypt’s President links Russian plane crash to terrorism – CNN
Russia’s initial resistance
Shortly after the crash, Western intelligence, particularly in Britain and the United States, pointed to a bomb having ruptured the plane. They said it may have been smuggled aboard in Sharm el-Sheikh, where the plane took off — possibly with help from an airport employee.
But initially, both Egyptian and Russian authorities resisted the idea that terrorists may have struck, perhaps retaliating for Russia’s support of Syrian President Bashar al-Assad.
Then, in November, the Russian Federal Security Service said a bomb with 1 kilogram (2.2 pounds) of explosives had detonated on board the plane. The government offered a $50 million reward for information leading to those responsible.
Russian investigators presented a soda can and circuitry as being components of the device, and after Russia’s announcement of the reward, its military flew multiple airstrikes over Raqqa, Syria, the de facto capital of ISIS’ proclaimed caliphate.
