Strongly hitting out at Pakistan for again raking up the Kashmir issue at the United Nations, India has said a constructive contribution cannot be expected from a country that has an established practice of hosting terrorists and is the "epicentre" of global terrorism, and the biggest destabilising force in the world.

World leaders thanked India for its help and support in combating the coronavirus pandemic through "early and meaningful" shipments of COVID-19 vaccine doses, as they addressed the high-level UN General Assembly session this year.

India slammed Pakistan at the UN after Prime Minister Imran Khan raked up the issue of Jammu and Kashmir in his address to the 76the UN General Assembly session on Friday.

A 26-year-old Sikh-American officer in the US Marines who has been allowed to wear the turban - the first person in the 246-year history of the elite force allowed to do so, but with a few limitations, plans to sue the Corps if he is not granted full religious accommodation, according to a media report.

"In all the meetings the Prime Minister had, beginning with US leadership, there was a suo moto recognition of the concerns that Pakistan represents as a country that has in many senses both supported and nurtured cross-border terrorism, including in Afghanistan and from Afghanistan," he said.

First Secretary Sneha Dubey gave a blistering retort to Khan in the UN General Assembly as she delivered India's strong Right of Reply from the UNGA hall, carrying on with a tradition seen over the past few years of young Indian diplomats taking on Pakistani leaders and strongly responding to their rants over Kashmir and other internal matters of India.

Shringla said India will continue to work towards the reformed United Nations during its stint as a non-permanent member of the UN Security Council.

Addressing the 76th United Nations General Assembly session here, Prime Minister Modi said that today, every sixth person in the world is an Indian.

Addressing the 76th UNGA session in New York, Modi called for ensuring that no country 'tries to take advantage of the delicate situation in Afghanistan and use it for its own selfish interests'.

"We keep hearing that Pakistan is a 'victim of terrorism'. This is the country which is an arsonist disguising itself as a fire-fighter. Pakistan nurtures terrorists in their backyard in the hope that they will only harm their neighbours," India's first secretary Sneha Dubey said in the UN General Assembly on Friday.

The nomination sets up a confrontation between the Taliban and Afghanistan's fallen government envoy, Gram Isakuzai, who has held his post so far.

The world is seeing an "explosion" in seizures of power by force and military coups are back, UN Secretary General Antonio Guterres told world leaders on Tuesday, lamenting that geopolitical divisions are undermining international cooperation as he called for strengthening global governance and re-igniting multilateralism.

Time's profile of Modi says that in its 74 years as an independent nation, India has had three pivotal leaders -- Jawaharlal Nehru, Indira Gandhi and Modi. "Narendra Modi is the third, dominating the country's politics like no one since them."

Modi will address world leaders from the iconic United Nations General Assembly hall on the morning of September 25, a day after he participates in the Quad Leaders' Summit in Washington, DC hosted by Biden on September 24.

September 11 is a "stark reminder" of the continuing threat of terrorism and the world must unite against this menace, India's Ambassador to the US Taranjit Singh Sandhu has said, as he paid homage to the victims of the terror attacks at the 9/11 Memorial here.

'Afghan people will not accept a governing structure that excludes women and minorities'

India has always provided very strong support to minority communities in Afghanistan, particularly Sikhs and Hindus, and it is an important part of New Delhi's effort to evacuate those Afghan nationals who want to leave the war-ravaged country, Foreign Secretary Harsh Vardhan Shringla has said.

Strongly condemning the terrorist strikes in Afghanistan's capital Kabul, India has told the United Nations Security Council that these attacks reinforce the need for the world to stand unitedly against terrorism and all those who provide sanctuaries to terrorists.

"Whether it is in Afghanistan or against India, groups like Lashkar-e-Taiba (LeT) and Jaish-e-Mohammed (JeM) continue to operate with both impunity and encouragement," India's external affairs minister S Jaishankar said

Stephane Dujarric, Spokesman for the Secretary-General Antonio Guterres, told reporters on Wednesday that the group of about 100 UN personnel from across the system travelled from Kabul to Almaty, where they will continue their work remotely.
