MINSK, Belarus (AP) — Belarusian authorities have released hundreds of people detained amid demonstrations contesting the results of the presidential election, in an attempt to assuage public anger against a brutal crackdown on peaceful protests.

Around midnight, scores of detainees were seen walking out of one of Minsk's jails. In the early morning, volunteers also saw at least 119 detainees being released in the сity of Zhodino just northeast of the Belarusian capital. Ambulances arrived to carry those who apparently were unable to walk on their own.

The releases came hours after Belarus' top law enforcement official apologized on state television for the indiscriminate use of force by police. “I take responsibility for what they say was violence against those people, who happened to be nearby and failed to back off quickly enough,” Interior Minister Yuri Karayev said late Thursday.

The apologies and the release of detainees follow five days of massive protests, in which crowds of demonstrators swarmed the streets to contest the vote results and demand an end to the 26-year rule of authoritarian President Alexander Lukashenko. On Thursday, thousands of workers rallied outside industrial plants to denounce the police crackdown and push for a recount of Sunday's vote.

Nearly 7,000 people have been detained and hundreds injured in the clampdown on demonstrators protesting the official results that said Lukashenko won 80% of the vote and his top opposition challenger only 10%. Police have broken up protests with stun grenades, tear gas, rubber bullets and severe beatings.

On Thursday, hundreds of women formed long “lines of solidarity” in several areas of the capital, Minsk. Many were dressed in white and carried flowers and portraits of detained loved ones.

The human chains grew throughout the day, filling Minsk's main central squares and avenues and spreading to numerous other cities as motorists honked in support. In Minsk and several other cities, thousands of factory workers also rallied against the police violence, raising the prospect of strikes in a new challenge to the government. Protesters were shouting "Go away!” to demand Lukashenko’s resignation.

Amid growing public dismay, dozens of military and police veterans posted videos in which they dumped their uniforms and insignia in the trash. Several popular anchors at Belarus’ state TV stations have quit.

The demonstrations have spread even though the protest lacks leaders. The top opposition challenger in the vote, Sviatlana Tsikhanouskaya, suddenly emerged Tuesday in neighboring Lithuania and called on her supporters to stop protests in a video that her associates said was recorded under pressure from law enforcement officials before she left. The 37-year-old former teacher had joined the race to replace her husband, an opposition blogger, who has been jailed since May.

The massive protests against election results and police brutality have been an unprecedented challenge to Lukashenko, who has been in power since 1994 and earned the nickname of “Europe’s last dictator” for his relentless crackdown on dissent. The scope and ferocity of the police clampdown were remarkable even for Lukashenko’s iron-fisted rule, triggering widespread anger.

After dismissing protesters as mostly ex-convicts and unemployed, the authoritarian leader kept silent Thursday as the demonstrations spread quickly. Some reports said he was preparing an address to the nation.

Belarusian upper house speaker Natalya Kochanova said late Thursday that more than 1,000 detainees had been released earlier in the day following Lukashenko's order to law enforcement agencies to look more closely into the detentions.

A protester died Monday in Minsk when, according to the Interior Ministry, an explosive device he tried to throw at police blew up in his hand. Media reports challenged the ministry's claim, alleging that he was killed by police. The place where he died quickly turned into a pilgrimage site, with hundreds of people, including European ambassadors, laying flowers there.

The authorities said that a detainee died in the southeastern city of Gomel, but the circumstances of his death weren’t immediately clear.

The brutal suppression of protests drew harsh criticism in the West.

European Union foreign ministers are set to meet Friday to discuss a response, and German Foreign Minister Heiko Maas said the 27-nation bloc would “increase the pressure” on Belarus.
