Tampa/IBNS: After nuke threat to India, now Pakistan Army chief Asim Munir has threatened to target billionaire Mukesh Ambani-led RIL's refinery in Gujarat's Jamnagar, media reports said.

Munir made the threat at a formal dinner in Tampa, Florida.

He referred to a social media post with a Quranic verse along with Ambani's picture to say he authorised it during the recent India-Pakistan conflict "to show them what we will do the next time", The Times of India reported.

Munir has also said his country will defend its water rights "at all costs" if India goes ahead with dam construction on the Indus River.

Munir said that Islamabad would not hesitate to plunge the region into nuclear conflict if the country faces an existential threat in a future war with New Delhi.

"We are a nuclear nation. If we think we are going down, we'll take half the world down with us," Munir said as quoted by NDTV.

Responding to Pakistan Army chief Asim Munir's nuke threat from the United States, India on Monday said "nuclear sabre-rattling" is Islamabad's "stock-in-trade".

Condemning Munir's remarks, India's Ministry of External Affairs (MEA) said it "won't give in to nuclear blackmail".

The MEA's statement reads, "Our attention has been drawn to remarks reportedly made by the Pakistani Chief of Army Staff while on a visit to the United States. Nuclear sabre-rattling is Pakistan’s stock-in-trade.

"The international community can draw its own conclusions on the irresponsibility inherent in such remarks, which also reinforce the well-held doubts about the integrity of nuclear command and control in a state where the military is hand-in-glove with terrorist groups."

"It is also regrettable that these remarks should have been made from the soil of a friendly third country. India has already made it clear that it will not give in to nuclear blackmail. We will continue to take all steps necessary to safeguard our national security," it added.
