On Sunday, armed attackers slit the throats of 11 miners in a residential compound near a mine site in Balochistan's Mach coalfield area, filmed the entire incident and later posted it online. The gruesome attack was claimed by the militant Islamic State group.

Since then, thousands of Hazaras have staged a protest along with coffins containing the miners' bodies in the western bypass area in Quetta, while members of the community have also held protests in other cities across the country.

Braving the biting cold, the mourners in Quetta, including women and children, have refused to leave until the premier visits and the killers are brought to justice. However, earlier today, Prime Minister Imran Khan appealed to the Hazara community to bury those killed in the attack, calling on them to refrain from "blackmailing the premier".

"We have accepted all of their demands. [But] one of their demands is that the dead will be buried when the premier visits. I have sent them a message that when all of your demands have been accepted [...] you don't blackmail the prime minister of any country like this," he said at a ceremony in Islamabad.

On Thursday, Traffic disruptions were reported in multiple areas of Karachi while operations of Pakistan International Airlines (PIA) were also affected due to the protests.

PIA spokesperson Abdullah Khan had said traffic congestion on the routes towards the Jinnah International Airport caused difficulty for passengers and staff trying to reach the airport.

Multiple PIA flights from Karachi to Lahore, Islamabad, Peshawar and Faisalabad were either cancelled or delayed by a few hours, the airline had said, urging passengers to stay in contact with its call centre for updates.
