MOSCOW: Two small explosions hit a Russian region neighbouring Chechnya just days before world leaders gather in Moscow to mark the 60th anniversary of the Soviet defeat of Nazi Germany, local media reported on Friday. No one was seriously injured in the blasts in Dagestan late on Thursday, the day the FSB security service said it had foiled Chechen rebel plans to attack towns in the north Caucasus region with poison and explosives. Itar-Tass news agency reported the explosions, 15 minutes apart, had been directed at policemen. Russian authorities have launched a tough security operation to guard against possible Chechen rebel attacks ahead of Monday's festivities, drafting thousands of police and troops into the capital and advising Muscovites to stay at home.
