The exiled head of Belarus' opposition urged European leaders to reject President Alexander Lukashenko's "fraudulent" reelection Wednesday as the EU held an emergency summit on the country's political crisis.

EU leaders at an emergency teleconference Wednesday underlined their concern about the contested presidential election and ratcheted up pressure on officials linked to the security crackdown that followed.

The EU believes that the results of the Aug. 9 polls, which handed Lukashenko his sixth term with 80% of the vote, "have been falsified," and the 27-nation bloc is preparing a list of Belarus officials who could be blacklisted from Europe over their roles.

"Our message is clear. Violence has to stop, and a peaceful and inclusive dialogue has to be launched. The leadership of Belarus must reflect the will of the people," European Council President Charles Michel tweeted, minutes after the summit he is chairing got underway.

Dutch Prime Minister Mark Rutte also tweeted: "The people of Belarus have the right to a result that accurately reflects their vote. The EU, including the Netherlands, can't accept the results of these elections."

Top EU diplomat Josep Borrell said Lukashenko "lacks democratic legitimacy" after an election victory that is not recognized.

The EU intends to express "condemnation and rejection" of Lukashenko's regime, Borrell told reporters in Santander, according to TV footage released by state broadcaster TVE.

Belarus security forces detained almost 7,000 people and injured hundreds with rubber bullets, stun grenades and clubs in the first four days of demonstrations. At least three protesters died.

Workers at state-controlled companies have joined strikes this week, as the unprecedented mass protests enter their 11th day and erode the authority of the man once dubbed "Europe’s last dictator."

It’s not entirely clear what the Europeans can do right now, but they appear determined to help maintain the momentum that began in the streets of Minsk with a show of political support and to revive a sanctions program on Belarus that was eased four years ago as relations with Lukashenko improved.

In a joint statement, the presidents of the Czech Republic, Hungary, Poland and Slovakia – countries known as the Visegrad Four – called on Belarus authorities to "open the way for a political solution and to abide by the fundamental human rights and freedoms while refraining from the use of violence against the peaceful demonstrators."

They urged unnamed "foreign actors to refrain from actions that would undermine Belarus‘ independence and sovereignty."

In a video statement ahead of the virtual EU summit, Belarusian opposition leader Sviatlana Tsikhanouskaya called on Europe to support "the awakening of Belarus."

"I call on you not to recognize these fraudulent elections. Mr. Lukashenko has lost all the legitimacy in the eyes of our nation and the world," Tsikhanouskaya said.

On the eve of the meeting, Michel had a half-hour telephone conversation with President Vladimir Putin to share the EU’s concern about election irregularities and the scale of the security crackdown and to impress upon the Russian leader the right of the Belarus people to determine their own future.

They discussed ways to encourage talks between Lukashenko and the opposition, possibly by supporting a dialogue process fostered by the Organization for Security and Co-operation in Europe.

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 the country.

"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.

Judy Dempsey, a nonresident senior fellow at Carnegie Europe and editor in chief of Strategic Europe, said the emphasis from the Europeans appears to be on getting Lukashenko to start talking to an opposition whose legitimacy he has tended to question.

"Time is of the essence," she warned if Belarusians are not to see their hopes for change hijacked.

"The EU already said it does not recognize the outcome of the presidential election. The idea of new elections would rattle Putin, whose own record on free and fair elections has been challenged – so far unsuccessfully – by protesters in Russia," Dempsey said.

The relatively small EU nation of Lithuania is playing a major role as the protests unfold by giving refuge to Tsikhanouskaya. Its Baltic neighbors, Estonia and Latvia, are also deeply involved in diplomatic efforts, as is Poland.

Some in Europe are concerned that hitting Lukashenko and his associates too hard might drive Belarus into the arms of Russia, even though relations between Minsk and Moscow have been troubled in recent years and even tenser in the run-up to the polls. Others fear Russian intervention.

But experts tend to downplay those worries and say the people of Belarus only want to secure independence and are not interested in deeper relations with Russia, the EU, or in joining Moscow’s nemesis, the NATO military alliance.

Belarus is not Georgia or Ukraine, where Putin fanned the flames of conflict by backing pro-Russian separatists.

Ekaterina Pierson-Lyzhina, a Brussels-based researcher into Belarus’ EU foreign policy, said that recent surveys suggest around 60% of people want the country to remain independent and reject any kind of union. Smaller groups are divided up into those who support European or Russian integration.

"There are no European flags, no Russian flags. This revolution is about domestic dissatisfaction of the majority of Belarusians with their president, who has held a grip on power for 26 years," she said and urged the EU to set up a fund for victims of the crackdown and help build a database on police crimes.
