Some journalists and media houses here have received a handwritten letter purportedly sent by militant groups, active in Kashmir, in this regard.
"Some so-called journalists in print and electronic media are presenting the struggle of Kashmiris in bad light," the letter said.
"We warn journalists to mend their ways or face dire consequences," said the letter issued under the name of Abu Irfan, a spokesman of the groups.
It warned the editors not to ignore the warning and publish it in their newspapers.
Inspector General of Police (Kashmir) S M Sahai said he would not be able to comment on the veracity of the letter as no one had reported the matter to the police so far.
