Long-serving Belarusian leader Alexander Lukashenko won a sixth term with 80.23% of the vote, the central electoral commission said on Monday, after police cracked down on opposition protesters.

In televised comments, Central electoral commission chief Lidia Yermoshina said that Lukashenko’s main challenger Svetlana Tikhanovskaya won 9.9%, citing a preliminary count.

The other three candidates each won less than two percent, Yermoshina said.

Police broke up crowds of protesters with stun grenades and rubber bullets in Minsk and other cities on Sunday evening after an exit poll showed Lukashenko winning an overwhelming victory. Following the protests, internet access was restricted in Minsk and other cities.

While other contenders were either jailed or kept off the ballot, Tikhanovskaya, a former teacher, stay-at-home mother and political novice, galvanised the opposition during the election campaign, attracting tens of thousands of supporters to the ex-Soviet country’s biggest demonstrations in years.  The 37-year-old ran for president after her husband Sergei, a political blogger, was detained and barred from the race.
