On Monday, Sri Lankan police found at least 87 detonators at a bus station in the neighbourhood of Colombo, the country's largest city by population.
Several days before Sri Lanka was shaken by a series of coordinated attacks that left 359 people dead and over 500 injured. The Islamic State terrorist organization (banned in Russia) reportedly claimed responsibility for the attacks on Tuesday. Sri Lanka launched a massive security operation in the wake of the tragedy.
