Russian police have arrested a group of people they said were planning a terror attack on Moscow, the country's anti-terrorism committee said Sunday, without giving details about the group's motives.
"After a series of investigations by the security services, a group of individuals was arrested in the west of Moscow suspected of planning a terrorist attack on the capital," the committee was quoted by local media as saying.
Investigators found about four kilograms (nine pounds) of homemade explosives in the suspects' apartment, the official TASS news agency reported.
More than 120 people were evacuated from the building and the explosives were defused.
Authorities did not give any details about the number of people arrested or their motives.
