At least 91 people, including 14 policemen, were killed and hundreds injured on Sunday in fierce clashes between protesters demanding Prime Minister Sheikh Hasina's resignation and the ruling party supporters in different parts of Bangladesh, forcing authorities to cut off mobile internet and enforce a nationwide curfew for an indefinite period.

The clashes broke out Sunday morning when protesters attending the non-cooperation programme under the banner of the Students Against Discrimination with the one-point demand of the government's resignation over a job quota system faced opposition from the supporters of the Awami League, Chhatra League, and Jubo League activists.

At least 91 people have been killed in clashes, shootings and counter-chases across the country surrounding the non-cooperation program, leading Bengali-language daily Prothom Alo reported.

According to the police headquarters, 14 policemen have been killed across the country. Of them, 13 were killed in Sirajganj's Enayetpur police station. One person was killed in Comilla's Elliotganj, the paper said. More than 300 policemen were injured.

The fresh round of clashes erupted days after over 200 people were killed in violent clashes between the police and mostly student protesters demanding an end to the controversial quota system that reserved 30 per cent of government jobs for relatives of veterans who fought in Bangladesh's War of Independence in 1971.

Today's protests were joined by unidentified people and activists of rightwing Islami Shashontantra Andolon, which erected barricades on several major highways and within the capital city, officials said, adding that protesters attacked the police stations and boxes, ruling party offices and residences of their leaders and burnt several vehicles.

The situation prompted authorities to order a curfew in major cities and small towns across Bangladesh for an indefinite period from 6 PM on Sunday, mobilising troops, paramilitary border guards BGB, and the elite anti-crime Rapid Action Battalion alongside police.

The government ordered the shutdown of Meta platforms Facebook, Messenger, WhatsApp and Instagram. The mobile operators were ordered to shut down 4G mobile internet, the paper added.

Meanwhile, Prime Minister Hasina said that those engaging in "sabotage" across the country in the name of protest are not students but terrorists and asked people to suppress them with a firm hand.

"I appeal to the countrymen to suppress these terrorists with a firm hand,” she said.

Hasina called a meeting of the National Committee on Security Affairs - the highest policy-making authority of national security - at Ganabhaban, the paper reported citing sources from the Prime Minister's Office (PMO). The meeting was attended by the chiefs of the Army, Navy, Air Force, police, RAB, BGB, and other top security officers. The meeting came as renewed violence spread to several parts of the country.

The government has announced a three-day general holiday on Monday, Tuesday and Wednesday to ensure public safety amid the ongoing violent protests across the country.

Giving details, the paper said eight people were killed in Feni, 22 including 13 policemen in Sirajganj, four in Kishoreganj, six in Dhaka, five in Bogura, three in Munshiganj, four in Magura, three in Bhola, four in Rangpur, three in Pabna, five in Sylhet, three in Cumilla, two in Sherpur and one in Joypurhat. One person was killed in Keraniganj, one in Savar and one in Barisal.

Six Awami League leaders and activists were beaten to death and several others injured in a clash between the ruling party supporters and protesters in Narsingdi, the paper reported.

In the capital, protesters took away the bodies of four people from Dhaka Medical College Hospital. The protesters went to the Central Shaheed Minar with the bodies of the four victims and chanted anti-government slogans, it said.

Citing Dhaka Medical College Hospital sources, the paper said 56 people were brought to the hospital with bullet injuries from Shahbagh, Shanir Akhra, Nayabazar, Dhanmondi, Science Laboratory, Paltan, Press Club and Munshiganj.

In a related development, a group of former senior military generals Sunday asked the government to withdraw the armed forces from the streets and send them back to barracks.

"We urge the government to undertake political initiatives to resolve the ongoing crisis. Do not destroy the good standing of our armed forces by keeping them engaged in a disgraceful campaign," said former army chief Iqbal Karim Bhuiyan, who served as the army chief under Prime Minister Hasina’s government.

Reading out a statement at a media briefing here, he said, "The Bangladeshi armed forces have never faced off with the masses or trained their guns at the chests of their fellow citizens." Another former army chief, octogenarian general Nuruddin Khan, who also served as the energy minister in Hasina’s past 1996-2001 tenure, was one of those who joined the briefing along with fellow officers, some of them being 1971 Liberation War veterans.

"Time is ripe to immediately take the soldiers to barracks to prepare themselves for any eventuality as the time taken to transition from internal security mode to operational mode takes quite some time,” the statement read.

Most of the shops and malls in Dhaka were closed amid the protest. Hundreds of students and professionals had gathered at Dhaka’s Shahbagh, blocking traffic on all sides.

Protesters had also gathered at the Science Lab intersection of the capital on the first day of the non-cooperation movement. They chanted anti-government slogans.

According to the Daily Star newspaper, several vehicles at Bangabandhu Sheikh Mujib Medical University (BSMMU) were torched on Sunday by unidentified people.

People carrying sticks were seen vandalising private cars, ambulances, motorcycles, and buses on the hospital premises, triggering fear among the patients, their attendants, doctors and staff, the paper said.

Nahid Islam, a coordinator of the anti-government protests, announced said they will stage a demonstration and mass sit-in on Monday to press home their one-point demand.

On Monday, they will unveil Martyrs' Memorial plaques across the country in memory of people killed recently centring the quota reform movement, he said in a statement.

There have been reports of vandalism and arson attacks on police vehicles and government buildings in multiple locations.

In Chattogram, the residences of Education Minister Mohibul Hasan Chowdhury Nowfel and Chattogram City Corporation Mayor Rezaul Karim Chowdhury, as well as the office of AL MP Md Mohiuddin Bachchu were attacked.

In an apparent retaliation, the homes of several Opposition Bangladesh Nationalist Party (BNP) leaders, including Standing Committee member Amir Khosru Mahmud Chowdhury, were targeted.

The BNP and its allies, along with numerous political, professional, and cultural groups have thrown their support behind the student-led movement that had been launched to demand reforms to quotas reserved for government jobs.

Prime Minister Hasina offered to sit for talks on Saturday with the coordinators of the Anti-Discrimination Student Movement. However, the movement's coordinators rejected the proposal.

The government leaders earlier claimed that the “peaceful campaign” was hijacked by fundamentalist Jamaat-e-Islami and their student front Islami Chhatra Shibir being backed by ex-premier Khaleda Zia’s BNP.
