In Belarus, police fired live ammunition, stun grenades and water cannons at anti-government protesters as demonstrations calling for the ouster of longtime authoritarian President Alexander Lukashenko continued for a fourth straight evening. The U.N. high commissioner for human rights called the police use of force excessive and a clear violation of international human rights standards, saying 6,000 people have been detained — including children — with at least two protesters killed by police.

In a harrowing video broadcast by Belarus state television, a half-dozen terrified protesters are shown lined up against a wall with injuries to their heads as, one by one, they promise to no longer take part in anti-government protests.

On Wednesday, hundreds of women dressed in white marched peacefully through the streets of Minsk demanding an end to police brutality.

Protester: “We stand against violence, against people getting beaten. We are standing against our children living in such a forceful state. We just want a bright future for us and our children.”
