MOSCOW - Russian special services eliminated two gunmen suspected of masterminding a terror attack in Moscow and arrested another, the National Anti-terrorism Committee (NAC) said Monday.

During the Federal Security Service's ambush, two militants were killed, the third was apprehended. One special forces' serviceman was also wounded.

"The militants neutralized in the town of Orekhovo-Zuyevo could conduct a terror attack at a mass event in the Russian capital downtown," spokesman for the NAC told local media.

The three Russians have arrived at this town, about 80 km east of Moscow, about a month ago following sabotage training in a Taliban camp in Pakistan, the Interfax news agency said.

There were no casualties among civilians, the NAC said.

President Vladimir Putin has been briefed about the counter-terror operation in the Moscow region, said Kremlin spokesman Dmitry Peskov.
