Russia to colour-code terror alerts
Russia's parliament is expected to pass a law creating colour-coded terror threat alerts in the wake of the fatal bombing of Moscow's Domodedovo airport.
The proposed law would institute a system similar to the one used in the United States since 2001, which Washington has announced will be abandoned by the end of April.
The measure had been on the State Duma's agenda for February, but the vote was brought forward after 35 people were killed this week when a bomb was detonated in the airport's international arrivals hall.
No-one has claimed responsibility for the bombing, and officials have not publicly identified any suspects, although media reports say investigators are focusing on insurgents from Russia's restive Caucasus region.
