Portugal Colonial - Bangladesh protesters set state TV HQ ablaze as toll mounts, internet cut

Police fired with rubber bullets at hundreds of protesters, who fought back and chased retreating officers to the headquarters of Bangladesh Television (BTV) in the capital Dhaka.

Demonstrators set ablaze the network's reception building and dozens of vehicles parked outside, with the broadcaster saying in a Facebook post that "many people" were trapped inside, although a station executive later told AFP they had safely evacuated the building.

A day earlier, Prime Minister Sheikh Hasina appeared on the network seeking to calm the escalating clashes.

"Our first demand is that the prime minister must apologise to us," protester Bidisha Rimjhim, 18, told AFP.

"Secondly, justice must be ensured for our killed brothers," she added.

Widespread internet outages went into effect, with websites for the Bangladesh home and foreign ministry, as well as the Dhaka Tribune and Daily Star newspapers, not available in the evening.

Bangladesh was experiencing a "near-total" internet shutdown, outage monitor Netblocks said, posting a graphic online showing connectivity plummeting late Thursday from around 90 percent to about 10 percent.

It said the latest outage "follows earlier efforts to throttle social media and restrict mobile data services" -- key communication tools for protest organisers.

Near-daily marches this month have demanded an end to a quota system that reserves more than half of civil service posts for specific groups, including children of veterans from the country's 1971 liberation war against Pakistan.

Critics say the scheme benefits children of pro-government groups that back Hasina, 76, who has ruled the country since 2009 and won her fourth consecutive election in January after a vote without genuine opposition.

Hasina's government has ordered schools and universities to close indefinitely as police step up efforts to bring the deteriorating law and order situation under control.

Her administration is accused by rights groups of misusing state institutions to entrench its hold on power and stamping out dissent, including by the extrajudicial killing of opposition activists.

Mubashar Hasan, a Bangladesh expert at the University of Oslo in Norway, said the protests had grown into a wider expression of discontent with Hasina's autocratic rule.

"They are protesting against the repressive nature of the state," he told AFP.

"Protesters are questioning Hasina's leadership, accusing her of clinging onto power by force," he added. "The students are in fact calling her a dictator."

- Gunshot injuries -

The premier appeared on BTV on Wednesday night to condemn the "murder" of protesters and vow that those responsible will be punished regardless of political affiliation.

But violence worsened on the streets despite her appeal for calm as police again attempted to break up demonstrations with rubber bullets and tear gas volleys.

At least 25 people were killed on Thursday in addition to seven killed earlier in the week, with hundreds more wounded, according to an AFP tally based on hospital data.

Police weaponry was the cause of at least two-thirds of those deaths, based on descriptions given to AFP by hospital figures.

"We've got seven dead here," an official at Uttara Crescent Hospital in Dhaka, who asked not to be named for fear of reprisal, told AFP.

"The first two were students with rubber bullet injuries. The other five had gunshot injuries."

Nearly 1,000 others had been treated at the hospital for injuries sustained during clashes, the official said, adding many had rubber bullet wounds.

Didar Malekin of the online news outlet Dhaka Times told AFP that Mehedi Hasan, one of his reporters, had been killed while covering clashes in Dhaka.

Several cities across Bangladesh saw violence throughout the day as riot police marched on protesters who had begun another round of human blockades on roads and highways.

Helicopters rescued 60 police officers who were trapped on the roof of a campus building at Canadian University, the scene of some of Dhaka's fiercest clashes, the elite Rapid Action Battalion police force said in a statement.

UN spokesman Stephane Dujarric appealed for "restraint from all sides".

"We urge the government to ensure a conducive environment for dialogue. And we encourage protesters to engage in dialogue to resolve the deadlock," he told reporters.

"Violence is never a solution."

- Social media 'weaponised'-

Before the late near-total internet shutdown, junior telecommunications minister Zunaid Ahmed Palak told reporters that social media had been "weaponised as a tool to spread rumours, lies and disinformation", forcing the government to restrict access.

Along with police crackdowns, demonstrators and students allied to the premier's ruling Awami League have also battled each other on the streets with hurled bricks and bamboo rods.

Rights group Amnesty International said video evidence from clashes this week showed that Bangladeshi security forces had used unlawful force.
