Police in Russia's province of Dagestan says a suicide bomber has killed policemen and injured six others at a traffic police post in northwest of the province. An unidentified driver blew himself up after officers at the post just outside the town of Khasavyurt asked him to pull over, AP quoted Dagestan's police spokesman Vyacheslav Gasanov as saying today. The Investigative Committee said in a statement on Thursday that it estimated the bomb to have contained between 100 and 120 k (220-265 pounds) of TNT.
