The United States has expressed concern over press freedom in Pakistan after a television channel considered to be sympathetic towards former Prime Minister Imran Khan was briefly blocked by the government.

“We are concerned that media and content restrictions, as well as a lack of accountability for attacks against journalists, undermine the exercise of freedom of expression,” US State Department spokesman Ned Price told reporters on Tuesday.

Price acknowledged the pressure on the popular television network that the Pakistani government has accused of “hateful, seditious and malicious content”.

“I know that your outlet, ARY, has not been immune to this constricted space. We routinely raise our concerns about press freedom to all stakeholders around the world, including to our partners and our counterparts in Pakistan,” he said.

After it was temporarily blocked in August, ARY had to let go of some of its senior presenters while one of its senior executives was briefly arrested.

Last week, Pakistani authorities indefinitely shut down Bol News, another news channel seen as supportive of Khan and his Pakistan Tehreek-e-Insaf (PTI) party.

The country’s media regulatory body said the channel was ordered to close because it “did not submit application for renewal of its licence”.

Sami Ibraham, president and managing director of the channel, told Al Jazeera there is pressure on the management to remove a few individuals from the company, including himself.

“On the face of it, it is the incumbent government exerting pressure, but we have not relented and not a single person has been removed,” he said.

Bol News has been controversial in the past as well. Its licence was revoked several times in the last few years following multiple complaints related to inciting violence and alleged hate speech by its anchors.

Khan was removed from office through a parliamentary vote of no-confidence in April. Since then, the cricketing icon-turned-politician has been holding massive public rallies demanding new elections.

On several occasions, the broadcast of his speeches on YouTube was allegedly blocked by authorities. Several journalists and media outlets considered close to Khan have witnessed a crackdown since April.
