Taking suo-motu cognisance of the incidents, the panel is also contemplating sending a sub-committee to assess the situation.
"PCI Chairman Justice C K Prasad has expressed grave concern over the death threats to editors and working journalists in Manipur from some underground and banned organisations in the recent days and sought a report from the Government of Manipur on the issue," the Council said in a press statement.
The action follows the reports of death threats received by Impact TV Editor-in-Chief Yumnam Rupachandra Singh from a militant organisation for not broadcasting a press note issued by it.
Concerned over their safety and threat to freedom of press, all the newspapers left blank space in the editorial column on 16 December and closed down publication of newspapers and stopped broadcast of news on 17 December.
It will thereafter explore the possibility of sending a sub-committee to assess the situation in Manipur and surrounding states, he said.
