India on Tuesday termed as "unfortunate" Pakistan's violation of ceasefire along the Line of Control in Jammu and Kashmir [Images] and appealed to Islamabad not to vitiate the atmosphere and disturb the peace process between the two countries.

"It would be my appeal to the Pakistani authorities to ensure that the ceasefire is maintained and both sides maintain peace and tranquility at the border," External Affairs Minister Pranab Mukherjee told reporters in Tehran.

Mukherjee, who is in Tehran for the Non-Aligned Movement ministerial meet, said all issues between India and Pakistan are being discussed within the umbrella of the composite dialogue process and that process should be allowed to continue.

"Nothing should be done to vitiate the atmosphere so that the dialogue process becomes disturbed," he said.

Asked whether the ceasefire violation had put the Indo-Pak relations in choppy weather, Mukherjee said, "I would not like to say that."

"The fact of the matter is unfortunately in the last few weeks occasions of violation of ceasefire have taken place and ceasefire is very important," he said.

Mukherjee noted that there have been incidents of violation of ceasefire earlier, but they have been dealt with at the local and the director general of military operations level.
