The European Union on Wednesday rejected the result of Belarus's disputed presidential election as strongman leader Alexander Lukashenko ordered his security forces to prevent any further unrest.
Following an emergency video conference, European Council chief Charles Michel said the EU would soon levy sanctions against a "substantial number" of people responsible for vote rigging and the violent suppression of protests in the ex-Soviet country.
Protesters have flooded the streets of Belarusian cities since the August 9 election, waving the red-and-white flags of the opposition and calling on Mr Lukashenko to step down after he claimed a sixth term with 80 percent of the ballot.
On Wednesday, protesters marched through central Minsk in the rain and gathered on Independence Square, chanting calls for Mr Lukashenko to "Leave!" They also called for major rallies on Sunday.
German Chancellor Angela Merkel told reporters that the EU rejects the results of the vote, which was "neither free nor fair".
Svetlana Tikhanovskaya, a 37-year-old political novice who fled to neighbouring Lithuania after claiming victory in the vote, earlier on Wednesday urged EU leaders not to recognise the "fraudulent" ballot.
"Lukashenko has lost all legitimacy in the eyes of our nation and the world," she said in the video appeal.
Western leaders including French President Emmanuel Macron and Merkel this week called on Mr Lukashenko's close ally Russia to foster talks between authorities and the opposition.
'No more riots': Lukashenko
The Kremlin on Wednesday described foreign interference in Belarus as "unacceptable" and Foreign Minister Sergei Lavrov condemned what he said were attempts from abroad to take advantage of unrest in Belarus.
"No one is making a secret of the fact that this is about geopolitics, the fight for the post-Soviet space," he said in a televised interview.
Yet Minsk's ties with Moscow have cooled in recent years after Mr Lukashenko resisted Russian President Vladimir Putin's efforts to integrate the two countries. Ahead of the vote, he accused the Kremlin of dispatching mercenaries to Minsk to stir unrest with the opposition.
Europe's longest-serving leader, Mr Lukashenko has resisted calls to resign or hold new elections and has accused the opposition of attempts to "seize power".On Wednesday he named a new cabinet, keeping key ministers in place including the Interior Minister Yury Karayev, who is responsible for police.

During a meeting of his security council, Mr Lukashenko ordered his government to prevent further unrest and shore up protections along the country's borders.
"There should be no more riots in Minsk. People are tired; people demand peace and quiet," Mr Lukashenko told officials.
He said the protective measures on the borders were necessary to stop "militants, weapons, ammunition and money from other countries from entering Belarus to finance the riots".
Tikhanovskaya, a trained English teacher who said she never planned to enter politics, contested the vote after her husband was jailed and barred from running against Mr Lukashenko.
Shot in the head
She has vowed to hold new elections and a Coordination Council which her allies created to oversee the transfer of power convened on Wednesday.
It called for new elections to be held "according to international standards" and an "immediate start of talks" with the authorities.
"If Belarus can solve the crisis without external intervention, that will be the best option," said Pavel Latushko, a former foreign minister who is on the council's presidium.
Ms Tikhanovskaya's campaign partner Maria Kolesnikova said they hoped for "friendly relations with all our neighbours, with EU countries and with Russia."
Nobel Prize-winning author and outspoken Mr Lukashenko critic Svetlana Alexievich is also on the presidium.
Polish Foreign Minister Jacek Czaputowicz met another of Ms Tikhanovskaya's campaign partners, Veronika Tsepkalo, in Warsaw and promised support.
Mr Lukashenko's claim of victory sparked the largest demonstrations in Belarus since it gained independence with the 1991 collapse of the Soviet Union.
More than 100,000 demonstrators flooded the streets of the capital Minsk last weekend as frustration reached a fever pitch.
A police crackdown on peaceful protesters in the days after the vote saw nearly 7,000 demonstrators detained and sparked allegations of abuse and torture at the hands of security services.
The health ministry on Wednesday confirmed the death of a 43-year-old man who was shot in the head during protests in the city of Brest.
Investigators said they were looking into the actions of the police who said they shot the man in self-defence.
Two other people are confirmed to have died in post-election unrest.
Pressure not to strike
Mr Lukashenko handed out awards to his security services for "impeccable service" after rights groups and Western leaders denounced police violence.
Traditionally loyal factory workers at state-run enterprises answered the opposition's calls to strike in an unprecedented display of anger towards the Belarusian leader.
But the authorities appear to be clamping down on Wednesday, with police arresting protesters at a demonstration outside the Minsk Tractor Works.
Police on Wednesday also blocked the entrance to the state Janka Kupala Theatre in Minsk after staff resigned en masse in protest at the sacking of its general director, Mr Latushko, who now sits on Ms Tikhanovskaya's coordination council.
