Pakistan's Inter-Services Intelligence (ISI) was sued by television channel Geo News on Friday for defamation over accusations of being anti-state.
Geo News is a part of the privately-owned Jang Group.
According to the Dawn, the channel has given the ISI 14 days to issue a public apology.
"Geo and Jang Group (have) served a legal notice on the Ministry of Defence, Inter-Services Intelligence and Pakistan Electronic Media Regulatory Authority for defaming and maligning the group," the channel said in a report published in a newspaper owned by the media house.
It further stated: "More than 8,000 journalists, workers and professionals attached to the group and their families are not only being harassed but also attacked and tortured across Pakistan."
The suing by Geo News was followed by a suspension of the channel's license for 15 days along with a fine of Rs.10 million.
