The protesters chanted "Go away" and waved white flags with a red stripe, a symbol of the Belarusian opposition.
Tens of thousands of Belarusians have demonstrated every weekend since the election, in which Lukashenko was declared the winner. His opponents say the vote was rigged, a charge denied by Lukashenko, who has been in
power for 26 years and has now turned to Russia for financial and other support to keep power.
On Sunday (October 11), 713 people were detained for taking part in mass protests, as security forces used water cannons and batons to break up crowds demanding a new presidential election.
European Union foreign ministers agreed on Monday (October 12) to sanction Lukashenko and other senior officials over what they said was a rigged election and worsening police violence against protesters.
Lukashenko was not on a EU sanctions list agreed on October 2 that targeted 40 names, but the bloc now says his refusal to consider new elections as a way out of the crisis leaves it with no choice.
