World leaders condemn Moscow subway attacks

World leaders are condemning the suicide bombingsthat occurred inMoscow's subway system Monday morning, killing 38 people and injuring dozens more.

Russia will "continue the fight against terrorism unswervingly and to the end," Russian President Dmitry Medvedev vowed Monday, shortly after the attacks.

Prime Minister Vladimir Putin, who built much of his political capital by directing a fierce war againstChechen separatists a decade ago, also said Monday that "terrorists will be destroyed."

U.S. President Barack Obamatold Medvedev by phone that the U.S. was ready to co-operate with Russia to help bring to justice those whowere behindwhat he called "heinous terrorist attacks."

And CanadianForeign Affairs Minister Lawrence Cannon said Canada "strongly condemns the cowardly attacks."

No group has claimed responsibility for Monday's attacks, but Alexander Bortnikov, the head of Russia's security agency, suggested that the attackscould beconnected to the restive Caucasus region that includes Chechnya.

Bortnikov said the assessment was based on fragments of the bombers' bodies. He did not provide any additional details.

Rush hour attack

Two female suicide bombers targeted two different stations during morning rush hour, police said.

The first blasthit around 8 a.m. local time at theLubyanka station in central Moscow. Thestation is beneath the building that houses the main offices of the Federal Security Service, or FSB, the KGB's main successor agency.

About 45 minutes later, a bomb went off at Park Kultury station,nearGorky Park.

In both cases, the bombs were detonated as the doors opened after the train pulled into the station, police said.

Shortly after the blasts, emergency officials told Russian news agenciesthat more than 100 people were injured,but they didn't provide a breakdown of casualties at each station.

Media reports released later suggestedthe number of wounded was closer to 65.

Igor Serebryany was in a train travelling through Park Kultury station in the opposite directionafter the blast.

"When our train arrived at Park Kultury on the opposite track across the platform, there was a wreckage of the train," he said.

"We were obliged to leave the station as soon as possible and the station was packed with policemen and special forces."

Police and security officialsare reviewing surveillance footage after reports suggestedthe women may have had accompliceswhen they enteredthe stations. It's not clear whether the suspected accomplices were men or women.

Moscow's subwaynetwork is one of the world's busiest, carrying about seven million passengers on an average weekday. Both stations were reopened late Monday afternoon,officials said.

Chechnya link probed

Last week, Russian police killed an Islamic militant leader in the North Caucasus region, where security officials have been clashing with militant forces.

The killings have raised fears of retaliatory strikes, and in February Chechen rebel leader Doku Umarov warned in an interview on a rebel-affiliatedwebsite that "the zone of military operations will be extended to the territory of Russia ... the war is coming to their cities."

Umarov also claimed his fighters were responsible for the November bombing of the Nevsky Express passenger train that killed 26 people en route from Moscow to St. Petersburg.

The last confirmed terrorist attack in Moscow took place in August 2004, when Chechen rebels claimed responsibility for an attack on the subway system.
