Russia’s security service, the FSB, has arrested four suspected terrorists from the North Caucasus who were preparing a bomb attack on public transportation in Moscow, FSB head Alexander Bortnikov told President Dmitry Medvedev on Monday.
“Just a few days ago we prevented a huge terrorist attack in the Moscow region. We arrested a criminal group of four people from the North Caucasus, who were preparing a terror attack on crowded transport hubs,” Bortnikov said.
Those arrested had an improvised bomb with a power equivalent to 10 kg of TNT, guns and maps showing the sites of their intended attacks, he said.
