The nuclear armed rivals have fought each other four times since independence, with three of the conflicts taking place over the disputed territory of Kashmir. India has faced an insurgency in Kashmir since 1989 from nationalist and Islamist elements which it has long accused Pakistan of stoking.
On Monday India submitted a dossier to the UN accusing Pakistan of systematically supporting terrorism within its territory.
One day later Pakistan submitted a similar document accusing India of backing terrorism in Pakistan.
Munir Akram, Pakistan’s UN ambassador, called on the international community to “take note of Indian terrorism and subversion against Pakistan and to prevail on India to desist from these illegal and aggressive activities”.
He claimed India is in violation of Security Council resolutions condemning terrorism and the UN Charter.
Earlier this month Imran Khan, Prime Minister of Pakistan, directly accused India of being involved with terrorism.
He commented: “We have provided irrefutable evidence of India’s state sponsored terrorism inside Pakistan.
“Details of financial & material support & Indian state’s direct involvement in terrorism have been given to the world which, in the face of this evidence, cannot remain indifferent or silent.
“We expect the international community to force India to end its terrorism & bring to justice those responsible for killing thousands of innocent people in Pakistan.
“Our resilient & courageous security agencies & forces will continue to give their all to protect our people.”
The remarks were greeted with a firm denial by Indian authorities.
In February 2019 tensions between India and Pakistan exploded into armed clashes along their contested border.
India conducted strikes inside Pakistan aimed at a militant group it blamed for a suicide car bombing which killed 40 Indian troops.
Pakistan retaliated and during the conflict an Indian F-15 fighter jet was shot down.
It’s pilot, wing commander Abhinandan Varthaman, was taken prisoner and later released back into Indian hands.
