India's Home Minister Rajnath Singh termed Pakistan a 'terrorist state' in an anti-Pakistan rant on Sunday, hours after suspected militants attacked an Indian army base in India-held Kashmir (IHK).

"Pakistan is a terrorist state and should be identified and isolated as such," Rajnath tweeted.

"I am deeply disappointed with Pakistan’s continued and direct support to terrorism and terrorist groups," the India's home minister said.

Rajnath's vitriol comes as Pakistan and India gear up for a showdown at the United Nations General Assembly (UNGA) session starting Monday.

Pakistan is preparing to "forcefully" highlight the situation in Indian occupied Kashmir at the UN session, whereas India intends to counter Pakistan's stance by raising the Balochistan issue, arguing that the Baloch are also seeking independence from Pakistan and deserve international support.

India is also backing Baloch activists to hold a demonstration outside the UN headquarters during the prime minister’s speech.

Both Pakistan and India are trying to persuade the US to support their respective positions. The US, however, appears to have decided not to take sides.

Pakistan has had to contend with incendiary remarks by Indian lawmakers with increasing frequency as both countries lock horns over the Kashmir issue.

In a speech on India's Independence Day, Prime Minister Narendra Modi in his address to the nation said, in a broadside against Pakistan, that the people of Balochistan, Gilgit Baltistan and Azad Jammu and Kashmir had thanked him.

Adviser to Prime Minister on Foreign Affairs Sartaj Aziz reacted to Modi's speech, saying the Indian PM was trying to divert global attention from the tragedy in India-held Kashmir, adding that Modi’s comments only proved Pakistan’s contention that India, through the Research and Analysis Wing (RAW), had been fomenting terrorism in Balochistan.

A day after Foreign Secretary Aizaz Chaudhry invited his Indian counterpart S Jaishankar for dialogue on the Kashmir dispute in August, Indian Defence Minister Manohar Parrikar told a rally in IHK that "going to Pakistan is the same as going to hell".

Days after Chaudhry's invitation, India formally rejected Pakistan's proposal to hold exclusive talks on the issue of Kashmir and said it will only discuss the issue of terrorism alleged infiltration of militants with Pakistan.

The FO on Saturday said that Pakistan's Permanent Representative to the United Nations in Geneva Ambassador Tehmina Janjua termed India’s attempts to deny its illegal occupation of Jammu and Kashmir is a "travesty of history".

"The sudden Indian focus on Balochistan is consistent with their playbook of seeking to distract attention from their repression in India-occupied Kashmir," the FO quoted Janjua as saying.

Kashmir clashes

Pakistan and India have been engaged in a back-and-forth over Kashmir since the killing of Hizbul Mujahideen commander Burhan Wani in IHK sparked violent protests against Indian rule despite the imposition of multiple curfews in the region, leaving at least 87 civilians dead and thousands others injured.

The unrest has lasted for more than two months as protesting residents clash almost daily with security forces in the worst such violence since 2010.

The Indian government has come under growing pressure over the level of casualties during the protests and over the security forces' use of shotguns loaded with pellets which can blind demonstrators.

The Foreign Office earlier this month urged the Indian government to listen to the international community and end bloodshed in IHK and asked the United Nations to send a fact-finding mission to IHK in order to investigate human right abuses.

India has slammed Pakistan's interference in Kashmir, terming it an 'internal matter'. Pakistan maintains the issue can only be resolved through dialogue and implementation of UN resolutions on Kashmir.

Indian army base attacked in IHK

A day before Pakistan and India are set to go head-to-head at the UN General Assembly, heavily-armed suspected militants killed 17 Indian soldiers in a pre-dawn raid on an IHK army base, the worst such attack for years in the disputed Himalayan region.

Soldiers searched the base, 100 kilometres west of the region's main city of Srinagar, for any more suspected militants, an Indian army statement said.

The Indian home minister held a high-level security meeting in New Delhi after saying he was cancelling his planned trips to Russia and the United States in the wake of the attack.
