India may have to "think of some other options" if ceasefire violations across the line of control (LOC) in Kashmir continued, news reports quoted Indian Air Force chief NAK Browne as saying Saturday.
Browne, the senior-most officer of India's armed forces, said: "We are watching the situation carefully, if the violations continue, perhaps we may have to think of some other options for compliance," NDTV news channel reported.
"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," Browne said speaking to reporters in New Delhi.
Browne refused to elaborate on what the other options may be.
"Options are options. We do not discuss these options openly. If the violations continue, we may have to look at the whole issue all over again."
The air chief's comments came against the backdrop of recent firing across the LOC, a de facto border dividing the disputed Kashmir region into areas administered by India and Pakistan.
India and Pakistan both have blamed each other for the violations of the ceasefire agreed to in 2003. The firings and alleged intrusions over the past week have resulted in the deaths of two soldiers on each side.
India's opposition Bharatiya Janata Party (BJP) has demanded that India recall its high commissioner to Pakistan and consider breaking off diplomatic relations.
Leaders of the ruling coalition have so far criticised Pakistan's actions but said there should be no knee jerk reaction.
Nuclear-capable neighbours India and Pakistan have had troubled relations since gaining independence from British rule in 1947 and have fought two of their three wars over Kashmir.
They are currently engaged in talks to resolve several contentious issues, including border disputes.
