Police in Belarus detained 345 people at nationwide anti-government protests on Sunday, the Interior Ministry said in a statement.
Thousands took to the streets of the Belarusian capital Minsk on Sunday, with police using stun grenades to disperse the crowd.
Opponents of President Alexander Lukashenko have staged regular protests since August, accusing him of rigging the election to extend his 26-year grip on power. He denies electoral fraud and has refused to resign.
