The Pakistan Electronic Media Regulatory Authority (Pemra) issued a notification prohibiting live coverage of the operation.
Pemra notification asked the channels to abide by clause 8 (8) of Electronic Media (Programmes and Advertisement) Code of Conduct 2015, show utmost sensitivity and refrain from coverage of the operation.
The operation was launched after Islamabad High Court (IHC) yesterday issued contempt of court notice against Interior Minister Ahsan Iqbal for failing to implement orders to clear the roads
About 2,000 activists of Tehreek-i-Khatm-i-Nabuwwat, Tehreek-i-Labaik Ya Rasool Allah (TLYR) and the Sunni Tehreek Pakistan (ST) for more than two weeks have been blocking the Islamabad Expressway and Murree Road that connect Islamabad with its only airport and the garrison city of Rawalpindi.
The protesters demand the resignation of law minister Zahid Hamid for changes made about Khatm-i-Nabuwwat or finality of prophethood oath in the Elections Act 2017 passed in September.
More than 70 people have been injured. They were shifted to hospital of twin cities of Islamabad and Rawalpindi, a health official said.
Those injured include also more than 35 security personnel who were hit by stones thrown by protesters, the official said.
Islamabad city magistrate yesterday issued a warning to protesters to disperse by midnight or face the consequences.
TV footage showed police firing teargas and security personnel in riot gears charging at the protesters.
Dozens of them were arrested and shifted to various police stations. Some of the security personnel were injured due to stone pelting by protesters.
According to a security official, more than 8,000 security personnel took part in the operation against around 2,000 protesters.
The operation was still going on and police were facing stiff resistance from the protesters.
Earlier, IHC last Friday had given a 24-hour deadline to the government to clear the roads, which was later extended till Thursday.
However, the court yesterday expressed strong displeasure at the government for failing to take action against the protesters.
