Pakistan Prime Minister Imran Khan.
Pakistani Prime Minister Imran Khan on Wednesday branded India an "oppressor and aggressor" a year after New Delhi imposed direct rule on Indian-administered Kashmir.
Protests were planned across Pakistan to mark the anniversary of New Delhi stripping Muslim-majority Indian Kashmir of its semi-autonomous status, a move that outraged Islamabad.
Kashmir, a disputed Himalayan territory, has been split since 1947 between India and Pakistan, both of which claim it in full and have fought wars over it.
"India stands exposed before the world, yet again, as an oppressor and aggressor," Khan said in a statement.
"Its so-called secular and democratic credentials stand fully discredited," he added, calling India's action last year a "crime against humanity".
Prime Minister Narendra Modi's government had promised the move would bring peace and prosperity to Indian Kashmir after three decades of violence sparked by an anti-India uprising.
Pakistan, however, has alleged it is a violation of the rights of Kashmiri people.
Khan accused India of trying to turn Kashmir's Muslim majority into a minority by ending restrictions on outsiders buying up property "in blatant violation of... UN Security Council Resolutions and international laws".
The change in rules has sparked fears that the Modi government is pursuing an Israel-style "settler" project.
A referendum in Kashmir mandated by a UN resolution in 1948 has never taken place.
Police were enforcing tight restrictions in Indian-administered Kashmir on Wednesday, where religious and political groups had called on residents to observe a "black day".
In the Pakistani capital Islamabad, a one-minute silence was held, along with a rally led by President Arif Alvi.
"India has learned from Israel how to change the demography (of Kashmir)," Alvi told the rally
Hundreds of billboards and banners displayed graphic images purportedly of human rights violations by Indian authorities in Kashmir.
Khan led a rally through Muzaffarabad, the capital of Pakistan-administered-Kashmir, where a few thousand people had gathered. He was due to address the region's legislative assembly.
Dozens of rallies are expected in other major Pakistani cities too.
On Tuesday, Pakistan released a new official map showing all of Kashmir as its territory.
Tensions spiralled between the nuclear-armed neighbours after India revoked Kashmir's autonomy and imposed movement and communications restrictions to quell unrest.
Pakistan has repeatedly likened Indian Prime Minister Narendra Modi to Adolf Hitler and called for international intervention.
The call to join protests on Friday repeated earlier demands from Khan for Pakistanis to begin holding weekly nationwide rallies until the prime minister departs for the United Nations General Assembly next month, where he vowed to act as an ambassador for all Kashmiris.
The decision comes at a time of high tension between the two nuclear-armed South Asian neighbours over the disputed Himalayan region of Kashmir.
"I want to give this message to Kashmiris that we stand by you and will continue to do so. It is sad that your independence struggle was presented as terrorism. Kashmir is our jugular vein and we will go to any lengths to protect it."
Slamming the move by the microblogging site, Pakistan Minister for Human Rights Shireen Mazari said: "Twitter has really gone too far in becoming mouthpiece of the rogue Modi govt! They sent a notice to our President! In bad taste and simply ridiculous."
In renewed airstrikes on Thursday, Israel destroyed a six-storey residential building in the heart of Gaza City. One man was killed by an Israeli missile fired east of Khan Younis in southern Gaza, medics said.
President Dr Arif Alvi and Prime Minister Imran Khan called on citizens to strictly adhere to anti-virus protocols while celebrating Eid Al Fitr, stating that the measures were necessary to avoid a massive outbreak.
Home Minister Mohammed Mahmood Ali was informed about the decision and he told the Muslim leaders that he would speak to the Director General of Police.
