MINSK: Belarusian demonstrators flooded the streets of the capital Minsk on Sunday, the final day of an ultimatum set by the opposition for the embattled strongman leader to resign after months of mass protests.

Videos taken by bystanders that were circulated by local media showed a convoy of buses carrying security personnel to the city centre along with metal cordons. A dozen metro stations in the centre of Minsk were closed to deter demonstrators from gathering and mobile internet was restricted.

Exiled opposition leader Svetlana Tikhanovskaya this month gave President Alexander Lukashenko a deadline of two weeks to resign, halt violence and release political prisoners, warning he would otherwise face a crippling general strike.

The 38-year-old political newcomer fled Belarus after claiming victory in an August presidential election that handed Lukashenko, 66, a sixth term and she has been rallying support from European leaders and calling for new elections.
