Pakistani Army Chief General Raheel Sharif on Sunday warned India of "unbearable cost" if it forces a war on Pakistan.

"Let me reiterate that our armed forces stand fully capable to defeat all sorts of external aggression... If the enemy ever resorts to any misadventure, regardless of its size and scale — short or long — it will have to pay an unbearable cost," said Sharif while addressing an event to mark the 50th anniversary of the 1965 war with India, reports PTI.

Sharif's statement was a response to Indian Army chief General Dalbir Singh Suhag remark made last week when he said that the Indian Army was prepared for "swift, short nature of future wars".

"Armed forces of Pakistan are fully capable of dealing with all types of internal and external threats, may it be conventional or sub-conventional; whether it is cold start or hot start. We are ready," said Sharif. 

Bringing up the issue of Kashmir, Raheel Sharif said that the state is an "unfinished agenda of partition" and needs to be resolved according to the UN resolution that recommended plebiscite to decide the future of of the disputed territory.

He further assured action against militants group in Pakistan. "I reiterate the resolve that we shall not relent until all terrorists, their financiers, abettors, facilitators and sympathisers are brought to justice," said Sharif.
