In a discussion program on NDTV today, Mattoo said he had personally visited homes of editors and apologised for alleged banning of newspapers saying there could have been a "miscommunication".
He also said from tomorrow, newspapers will resume printing in the Valley and they can publish whatever they feel without any "censorship or ban of anykind".
"I can say with all the responsibility that there was no ban. I think there was some miscommunication; obviously there was a curfew but the newspapers can publish, as they have done, online or print edition.
According to Mattoo, at a suitable time there has to be a clarification and "heads will roll" on who communicated this decision and who took that action.

"The fact of the matter remains that in this day and age, no matter how grave the situation is, if someone took a decision or communicated a decision or miscommunicated something like this, once the crisis is over obviously we will have to take action against that person and I can say this with responsibility that I have as advisor to the Chief Minister," he said.
"I can't comment on Shujaat's version. I have personally gone to main editors' houses and apologised if there was a miscommunication and if misinformation. All I can say that it was not done with the consent of the Chief Minister of the state," Mattoo said.
