Violence in India-controlled Kashmir could increase if the international community does not pay attention to the developments in the disputed area, said Pakistani Prime Minister Imran Khan on Thursday.

Khan expressed his concern on his Twitter account over the developing situation in Kashmir following the Indian government's decision on Aug. 5 to revoke the special status of India-controlled Kashmir.

After India's decision, Pakistan in reaction downgraded its diplomatic ties and suspended trade relations and train service with India.

The Pakistani prime minister said India has sent extra troops to Kashmir, which he said is "an already heavily militarized" area, and a curfew has been in place in India-controlled Kashmir for 12 days.

On Wednesday, Khan visited Pakistan-controlled Kashmir amid the ongoing tensions and addressed the legislative assembly of Pakistan-controlled Kashmir.

He said his country will appeal to the United Nations (UN) and the International Court of Justice to win rights for the people of India-controlled Kashmir.

Reports said the UN Security Council will hold a session in New York on Friday to discuss the Jammu and Kashmir dispute.

Discussions on Kashmir in the Security Council after four decades will be a landmark diplomatic achievement, Pakistani Foreign Minister Shah Mahmood Qureshi said Thursday.

Pakistan observes a "black day" at the official level on Thursday on the occasion of India's Independence Day. Rallies are being held in major Pakistani cities and towns against the Indian government's decision to abolish India-controlled Kashmir's special status.
