European parliamentarians Ryszard Czarnecki and Fulvio Martusciello have slammed Pakistan for harbouring militants, with one of them saying terrorists who carried out attacks in India did not come from the Moon.

During a special debate of the plenary of the European Parliament on the situation in Kashmir on Tuesday, Czarnecki, the member of EU Parliament and European Conservatives and Reformists Group in Poland called India the "greatest democracy of the world".

"India is the greatest democracy of the world. We need to look at terrorist acts that took place in India, Jammu and Kashmir. These terrorists didn't land from the Moon. They were coming from the neighbouring country. We should support India," said Czarnecki.

Martusciello, a member of EU Parliament and Group of European People's Party (Christian Democrats) in Italy, said Pakistan had threatened to use nuclear weapons which was a concern to the European Union.

"Pakistan is somewhere where terrorists have been able to plan bloody terrorist attacks in Europe," said Martusciello while accusing Islamabad of human rights violations.

Opening the debate on behalf of the vice president of the European Commission, Federica Mogherini, EU Minister Tytti Tuppurainen said 'no one could afford another escalation in Kashmir.'

The EU minister urged India and Pakistan to resolve Kashmir issue through dialogue, seeking a peaceful and political solution, respectful of the interests of the Kashmiri population on both sides of the Line of Control.

"This is the only way to solve the longtime dispute to avoid instability and insecurity in the region, she added," she said.

She also called on India to restore means of communications in the Valley.

India revoked Jammu and Kashmir's special status on August 5. Reacting to India's move on Kashmir, Pakistan downgraded diplomatic ties with New Delhi and expelled the Indian High Commissioner.

Pakistan has been trying to internationalise the Kashmir issue but India has asserted that the abrogation of Article 370 was its "internal matter". New Delhi also asked Islamabad to accept the reality and stop its anti-India rhetoric.

India has defended imposition of restrictions in the Kashmir Valley on the grounds that they were put to prevent Pakistan from creating more mischief through proxies and terrorists.
