During the annual march commemorating the victims of Stalinist purges seven activists of the opposition were detained by police as The Associated Press news agency reports.
About 1,000 people took part in the authorized march. Some participants carried posters with the slogans: "No to Union with Russia!" and "Union with Russia Means Hunger and Killings." Several hundred police were present to monitor the gathering. At the same time police did not confirm the detention of the oppositionists.
The marchers followed from downtown Minsk to a site of Soviet-era mass executions carrying 12 wooden crosses which they set up at the Kuropaty mass grave site, where about 100,000 people were shot dead between 1937 and 1941.
"Political repressions in Belarus continue and Kuropaty reminds Belarusians what frightening consequences tyranny leads to," Mikola Kryzhanovsky, from the opposition Conservative-Christian party, told to the marchers.
