The report is "under the active consideration of the government" and appropriate action would be initiated against the guilty, Information and Broadcasting Minister Manish Tewari said.
The Left chose not to link the report and the politics over it, saying it was a national security issue.
Communist Party of India leader Gurudas Dasgupta said: "I would not link it with any political development. The issue is more important because it concerns the defence and security of the country."
He, however, questioned the delay in taking action, on the part of the government. "If the army had sent the report to the defence ministry, why has it been put on hold for a long time? The whole thing speaks of severe laxity and ignoring the interest of the nation," Dasgupta said.
