Hours after a deadly blast ripped through a Moscow subway, the New York Police Department announced it is sending a team of officers to the Russian capital. Correspondent Jenny Falcon has more from New York.
This is not the first time the New York Police Department has sent units outside of the United States, as part of recent counter-terrorism efforts. Since the September 11, 2001, terrorist attacks in the United States, New York police have traveled to Britain, Canada and Israel.
The New York Police Department (NYPD) said in a statement that the team's mission is to "observe and gather information on the Moscow subway bombing."
More than three-dozen people were killed, and more than 100 wounded in the explosion and subsequent fire.
Russian officials have suggested that they blame Chechen rebels, but Chechen leaders have denied responsibility for the blast, which authorities suspect was a suicide bombing.
The team of New York police will consist of officers from New York's intelligence division and transit bureau.
New York police use routine patrols, dogs and plain clothes officers to try to secure the city's busy and often crowded trains and subway stations. New York City has one of the largest subway systems in the world, with over 1,000 kilometers of track.
New York has remained on a heightened state of alert for future attacks, since the 2001 attack on the World Trade Center.
