Asserting that repeated ceasefire violations by Pakistan are "unacceptable", IAF chief Air Chief Marshal NAK Browne today warned that India may have to look at "some other options for compliance" if such incidents continue.

"We have a Line of Control, we have a ceasefire agreement, we have certain structures and mechanisms which are sacrosanct and any violation of these with impunity especially what has been happening in the last few months is totally unacceptable.
