A Belarus opposition leader has reportedly been detained at the border with Ukraine the day after her disappearance.
State media report that Maria Kolesnikova was held at the border early on Tuesday morning.
This comes a day after witnesses reportedly saw masked men bundle her into a minibus.
Kolesnikova is one of three women who joined forces to challenge President Alexander Lukashenko in August’s election.
Lukashenko’s re-election was followed by mass protests amid allegations of vote-rigging. According to authorities more than 600 people were arrested on Sunday on the fourth consecutive weekend of anti-government demonstrations.
Lukashenko has ruled the country since 1994. He has accused Western powers of interference.
He has been supported by President Vladimir Putin of Russia and is expected to visit Moscow “in the coming days”.
