Nina Bahinskaya, 73, is bundled into a van by a masked officer

A 73-year-old opposition figurehead in Belarus was once again among dozens of women arrested during a protest against embattled President Alexander Lukashenko.

Thousands of people gathered in Minsk on Saturday to demand the resignation of Mr Lukashenko, whom they accused of rigging the presidential elections last month.

Among the demonstrators was Nina Bahinskaya, a great-grandmother who has become an icon of the protest movement.

Video footage on social media showed a masked officer ripping a red and white flag from her hands before packing her into a van.

Ms. Bahinskaya, who was arrested during earlier protests against Lukashenko, was later released, local media reported.
