Pakistan's National Security Committee has decided to downgrade diplomatic ties and suspend trade with India. The Hindu-nationalist government in India abolished the autonomous status of its part of Kashmir on Monday.
Senior military and government officials including Prime Minister Imran Khan made the decision at a National Security Committee meeting.
A separate government statement said the country would also suspend its trade with India and review other aspects of the relationship.
Pakistan's parliament passed a motion calling on the United Nations to pressure India to reverse its decision.
Provoking Pakistan
Both countries and China claim parts of Kashmir. India drew fierce rebukes from Pakistan and China on Monday after it unexpectedly revoked its portion of Kashmir of its autonomy.
Jammu and Kashmir, as the Indian-controlled part is known, was previously able to make its own laws because it was exempt from some parts of India's constitution.
Critics accused the Hindu-nationalist government of trying to promote the share of Hindus in the Muslim-majority state. The former special status had blocked Indians from other areas of the country from owning property there.
The government said the special status had hampered Kashmir's development and integration with the rest of the country.
Simmering conflict
The region has been on lockdown since Monday amid concerns about widespread protests against the government's decision. Internet and telephone services remain blocked late on Wednesday.
Pakistan and India have fought two wars over Kashmir since they became independent from the British empire in 1947.
India accuses Pakistan of supporting Islamist insurgents in Jammu and Kashmir. Pakistan denies the allegation.
India-Pakistan rivalry: Kashmiris pay a high price
India and Pakistan continue to clash over Kashmir, a volatile Himalayan region that has been experiencing an armed insurgency for nearly three decades. Many Kashmiris are now fed up with both Islamabad and New Delhi.

An unprecedented danger?
On February 27, Pakistan's military said that it had shot down two Indian fighter jets over disputed Kashmir. A Pakistani military spokesman said the jets were shot down after they'd entered Pakistani airspace. It is the first time in history that two nuclear-armed powers have conducted air strikes against each other.

India drops bombs inside Pakistan
The Pakistani military has released this image to show that Indian warplanes struck inside Pakistani territory for the first time since the countries went to war in 1971. India said the air strike was in response to a recent suicide attack on Indian troops based in Jammu and Kashmir. Pakistan said there were no casualties and that its airforce repelled India's aircraft.

No military solution
Some Indian civil society members believe New Delhi cannot exonerate itself from responsibility by accusing Islamabad of creating unrest in the Kashmir valley. A number of rights organizations demand that Prime Minister Narendra Modi's government reduce the number of troops in Kashmir and let the people decide their fate.

No end to the violence
On February 14, at least 41 Indian paramilitary police were killed in a suicide bombing near the capital of India-administered Kashmir. The Pakistan-based Jihadi group, Jaish-e-Mohammad, claimed responsibility. The attack, the worst on Indian troops since the insurgency in Kashmir began in 1989, spiked tensions and triggered fears of an armed confrontation between the two nuclear-armed powers.

A bitter conflict
Since 1989, Muslim insurgents have been fighting Indian forces in the Indian-administered part of Kashmir - a region of 12 million people, about 70 percent of whom are Muslim. India and Pakistan have fought two of their three wars since independence in 1947 over Kashmir, which they both claim in full but rule in part.
India strikes down a militant rebellion
In October 2016, the Indian military has launched an offensive against armed rebels in Kashmir, surrounding at least 20 villages in Shopian district. New Delhi accused Islamabad of backing the militants, who cross over the Pakistani-Indian "Line of Control" and launch attacks on India's paramilitary forces.

Death of a Kashmiri separatist
The security situation in the Indian part of Kashmir deteriorated after the killing of Burhan Wani, a young separatist leader, in July 2016. Protests against Indian rule and clashes between separatists and soldiers have claimed hundreds of lives since then.

The Uri attack
In September 2016, Islamist militants killed at least 17 Indian soldiers and wounded 30 in India-administered Kashmir. The Indian army said the rebels had infiltrated the Indian part of Kashmir from Pakistan, with initial investigations suggesting that the militants belonged to the Pakistan-based Jaish-e-Mohammad group, which has been active in Kashmir for over a decade.

Rights violations
Indian authorities banned a number of social media websites in Kashmir after video clips showing troops committing grave human rights violations went viral on the Internet. One such video that showed a Kashmiri protester tied to an Indian army jeep — apparently as a human shield — generated outrage on social media.

Demilitarization of Kashmir
Those in favor of an independent Kashmir want Pakistan and India to step aside and let the Kashmiri people decide their future. "It is time India and Pakistan announce the timetable for withdrawal of their forces from the portions they control and hold an internationally supervised referendum," Toqeer Gilani, the president of the Jammu and Kashmir Liberation Front in Pakistani Kashmir, told DW.

No chance for secession
But most Kashmir observers don't see it happening in the near future. They say that while the Indian strategy to deal strictly with militants and separatists in Kashmir has partly worked out, sooner or later New Delhi will have to find a political solution to the crisis. Secession, they say, does not stand a chance.
