The protesters, many dressed in the red-and-white colors of the opposition, chanted "fraudsters" as they marched, including through the capital Minsk.

However, many of them were arrested and taken away in vans by masked police who used force, grenades and tear gas to disperse the protesters. 

According to human rights activists, at least 53 people were abducted during Sunday's protests, Reuters reports.

"People's installation"

Today's demonstrations have been called by many "the installation of the people" by Svetlana Tichanovskaya, the opposition leader who fled to Lithuania after the criticized election on August 9.

"We have come to celebrate the installation of the people by the people's president," Alexander, a 30-year-old logistics worker demonstrating in Minsk, told Reuters. 

- First he forged the election and then he forged the installation.

Mr Lukashenko has been accused by the opposition of electoral fraud and many countries, including the EU, US and UK, have refused to recognize Lukashenko as the winner.

On Wednesday, Lukashenko was installed without warning for a sixth term as president, leading to renewed protests, including internationally.

"Lukashenko must leave"

More and more international voices are now being raised for Lukashenko to resign.

Most recently, French President Emanuel Macron has demanded his resignation.

"We are witnessing a power crisis in Belarus with an authoritarian administration that can not accept the logic of democracy," Macron said in a newspaper interview on Sunday.

- It is obvious that Lukashenko must go.

Russia, Belarus' ally, has said that the EU's and other countries' refusal to recognize Lukashenko as the country's legitimate president violates international law and is a direct interference in Belarus' internal affairs.
