Indian authorities have sent 50 Pakistani students and their teachers back to Lahore from New Delhi, after the recent row, which has raised tensions.

According to details, an Indian NGO had invited a delegation of 50 Pakistani students and their teachers to India. The delegation of Pakistani students and teachers arrived in India on May 1.

They were scheduled to go on a day-long trip to Agra on Wednesday and participate in an exchange of experiences with Indian students Thursday at the Pakistan Embassy.

However, the Indian government apparently buckled in the face of extremists and sent back the delegation to Lahore. The NGO that had invited the Pakistani delegation was also reportedly threatened.

The Indian government said it was not an 'appropriate' time to host the Pakistani students.

The students and their teachers arrived at Wagah Border amid tight security provided by Indian police due to threats from Indian hardliners.

Routes2Roots, the Indian NGO which had invited Pakistani students said in a statement, keeping in view the security, the delegation has been sent back to Lahore safely.
