Imphal: Editorials of all newspapers in Manipur on Tuesday went blank in protest against continuous threats by militants.

Militants of different outfits have been threatening the local media for not publishing their statements and also for giving space to their opponents, a spokesman of the All
Manipur Working Journalists' Union (AMWJU) said.

A militant outfit had planted a powerful grenade at the premises of a popular daily with a letter reading "editor this is the last warning next time the grenade would be exploded," on Monday.

"This is too much. Please allow us to work freely,"  the AMWJU spokesman said adding that the editorial columns were kept blank in protest against such armstwisting.

He said AMWJU had asked the government to provide security to the media houses but the latter had failed.
