There's a nervous calm on the streets of Kazakhstan’s biggest city, Almaty. President Kassym Jomart-Tokayev has appeared on television, confirming that anyone who comes out to protest will be shot by security forces. He's referred to anti-government demonstrators as bandits and terrorists. Having asked for external assistance to restore order, troops from Russia and neighbouring states have begun to arrive in what's being called a peace keeping operation. Our Europe correspondent, Simon McGregor-Wood reports.
