A suspected bomb went off at a bus stop near an academy of the Federal Security Service (FSB) in Moscow on Wednesday, the National Antiterrorist Committee said.
The explosion took place about 4:30 p.m. local time (13:30 GMT), "in direct proximity to the FSB Academy on Michurin Avenue," a law enforcement source said.
There were no casualties but some of the cars parked next to the stop "were slightly damaged."
A team of FSB investigators is currently working at the scene.
An FSB source told RIA Novosti that the explosive device was equivalent to 200 grams of TNT and that investigators are searching for another explosive device in the neighborhood.
He said the bomb detonated "when students began leaving the academy's premises."
Viktor Biryukov, a spokesman for the Moscow City Internal Affairs Main Administration, said security was beefed up in the Russian capital following the blast, said
Police patrols are paying special attention to public transportation stops, as well as in the capital's subway system.
