Belarusian activists say security forces have detained at least a dozen people as police broke up a protest march by pensioners demanding the resignation of Alyaksandr Lukashenko.

More than 1,000 pensioners gathered in Minsk on November 30 to stage what they called a “March of Wisdom”. But the demonstrators were divided into smaller groups that marched in different directions after being blocked by police along their planned route.

At least 30 people were detained in the November 30 crackdown, according to the Minsk-based Vyasna human rights center.
