Pakistan's leading television news channel has gone off the air in army cantonments and is facing interruptions in other areas across the country, its management said on Monday.
The partial blockade of the country's most viewed private channel comes amid reports that the powerful military is seeking to silence criticism of its alleged political role.
"Our broadcast is interrupted ... in most areas, almost 80% of the country," said the Geo network's president, Imran Aslam. "It is like economic strangulation," he told DPA.
Geo is seen as sympathetic towards former prime minister Nawaz Sharif, who was removed by the country's Supreme Court for alleged corruption that also involved his family.
Analysts say Sharif might have been the target of collusion between the generals and judges for calling for a civilian administration's supremacy in a country that has been ruled by the army for almost half of its existence.
The government denied ordering the blockade that started two weeks ago and asked the Pakistan Electronic Media Regulatory Authority (PEMRA) to make sure that broadcasts remain uninterrupted.
But there has not been any change, said a Geo journalist who asked not to be named. "There is enormous pressure by the military to follow their line in editorial content," said the journalist.
Cable operators said they face pressure from military spy agencies to either keep Geo blocked or change its position, making it hard for viewers to watch it.
