ISLAMABAD: Pakistan this week decided to close its shipping ports for Indian flag carriers, a statement from the country’s maritime affairs ministry said, as Islamabad’s tensions with New Delhi continue to surge following a deadly attack on tourists. 

The move came hours after India announced on Saturday it had banned the import of goods coming from or transiting via Pakistan and barred Pakistani ships. 

Both nations have taken a raft of measures against each other since Apr. 22, when gunmen killed 26 tourists in Indian-administered Kashmir. New Delhi pinned the blame on Islamabad, an accusation that Pakistan has vehemently denied and called for a transparent, international probe into the incident. 

Pakistan’s maritime affairs ministry said its decision to ban Indian ships from Pakistani ports has been taken to “safeguard maritime sovereignty, economic interest and national security.”

“Indian Flag Carriers shall not be allowed to visit any Pakistani port,” the statement said. “Pakistani Flag Carriers shall not visit any Indian Port. Any exemption or dispensation shall be examined and decided on case to case basis,” it added.

Trade between India and Pakistan has dwindled over the last few years. India announced on Saturday that it was banning Pakistani ships to ensure the safety of its assets, cargo and connected infrastructure, in the public interest and in the interest of the Indian shipping industry.

Both countries have been trading fire at the Line of Control frontier in Kashmir, which acts as a de facto border between India and Pakistan, for the last 10 days as per international media reports. 

Since gaining independence from British colonial India in 1947, India and Pakistan have fought two out of three wars over the disputed Himalayan region of Kashmir. Both countries claim it in full but administer only parts of it. 

The US, China, UK, Saudi Arabia, Turkiye, Iran and several other nations have called on both nuclear-armed neighbors recently to de-escalate tensions and avoid a military standoff. 

Pakistan has vowed it would issue a “strong” response if the Indian military attacks. India’s PM Narendra Modi this week gave his country’s military “operational freedom” to respond to the Apr. 22 attack.
