NEW DELHI -- The Latest on India's security clampdown in Kashmir (all times local):
U.N. Secretary-General Antonio Guterres is calling on India and Pakistan to refrain from taking any steps that would affect the status of Kashmir.
U.N. spokesman Stephane Dujarric told reporters Thursday "the position of the United Nations on this region is governed by the Charter of the United Nations and applicable Security Council resolutions."
Dujarric reiterated that statement when asked if the secretary-general supports the Security Council's call for a plebiscite on the future of Kashmir.
He said Guterres also recalls the 1972 Simla agreement on bilateral relations between India and Pakistan "which states that the final status of Jammu and Kashmir is to be settled by peaceful means, in accordance with the Charter of the United Nations."
He said the secretary-general "is also concerned over reports of restrictions on the Indian-side of Kashmir, which could exacerbate the human rights situation in the region," and reiterates his call for "maximum restraint."
Indian Prime Minister Narendra Modi says the downgrading of Indian-administered Kashmir from a state to a federally controlled territory will help end decades of terrorism and separatism incited by archrival Pakistan.
In a nationally broadcast speech Thursday, Modi described changes imposed this week by his government in Kashmir as historic and assured its residents that the situation will soon become normal.
Hindu-majority India has imposed an unprecedented security lockdown and a near-total communications blackout in the Muslim-majority region while revoking its special constitutional status.
It downgraded the divided region from statehood to a territory, limited its decision-making power and eliminated its right to its own constitution.
Modi said the "mainstreaming" of the Kashmiri people with the rest of the nation would expedite development and create new jobs with investment from public and private companies.
He accused Pakistan of using the past arrangement "as a weapon to incite people of the region against India," and said he has complete faith that the new system will be able to free Kashmir from terrorism and separatism.
An opposition Congress party lawmaker says security forces have prevented him from visiting the Indian-administered portion of Kashmir, causing him to return from its main airport after spending several hours there.
Lawmaker Ghulam Nabi Azad says he flew to Srinagar on Thursday to assess the situation in Muslim-majority Kashmir after the imposition of a media and security clampdown during the revocation of its special constitutional status by Prime Minister Narendra Modi's Hindu nationalist-led government.
Azad told reporters on his return to New Delhi that he was not allowed to meet party leaders in Kashmir.
Pakistan says it is still committed to continue talks about the opening of a visa-free border crossing to allow pilgrims to visit a Sikh shrine just inside the Islamic nation despite increasing tension with New Delhi over Kashmir.
Foreign Minister Shah Mahmood Qureshi made the announcement Thursday, saying Islamabad respects all religions.
Pakistan and India have held several rounds of talks on the plan to give special permits to devotees to access the shrine, the Gurdwara Darbar Sahib. Guru Nanak, the founder of the Sikh religion, settled in what is now Pakistan's Kartarpur, where he spent the last 18 years of his life.
The shrine was built after Guru Nanak died in the 16th century and is visible from the Indian side of the border.
Pakistan's foreign minister says Islamabad is not considering any military actions and instead is looking at political and legal options to challenge India's changes to disputed Kashmir's status.
Shah Mahmood Qureshi made the remarks Thursday at a news conference in Islamabad.
He says he will soon travel to China to inform Beijing about the situation after India downgraded the special status of Kashmir, a Himalayan region claimed by both Pakistan and India.
He rejected New Delhi's claim that the changes were its internal matter and that Islamabad should reconsider its expulsion of India's ambassador and suspension of trade and a key train service.
He said Pakistan might review its steps if New Delhi also agrees to do the same about its changes in Kashmir.
Pakistan says it has suspended a key train service with neighboring India over change in Kashmir's special status by New Delhi.
Federal Minister for Railways Sheikh Rashid Ahmad says the Express, or Friendship Express, train service is suspended from Thursday.
The latest move comes a day after Pakistan downgraded its diplomatic ties with India and suspended trade in response to New Delhi's decision to reduce the special status of Kashmir, a Himalayan region claimed by both countries.
The railway suspension announcement was made as passengers were waiting to board a train in the eastern city of Lahore to travel to India.
An opposition activist has filed a petition in India's top court challenging the communications blackout and security clampdown in the Indian-controlled portion of Kashmir, where people remained holed up in their homes for a fourth day.
State-run All India Radio says security agencies have arrested more than 500 people in the region apparently to prevent any outbreak of violence.
India's government this week revoked the special status of Jammu and Kashmir and downgraded the Himalayan region from statehood to a territory. Muslim-majority Kashmir is claimed in full by both India and Pakistan, and rebels have been fighting Indian rule in the portion it administers for decades.
India's National Security Adviser Ajit Doval visited Kashmir on Wednesday to assess the law and order situation.
