Islamabad: Amid talk of a possible extradition treaty, India has renewed its request for extradition of Mumbai underworld don Dawood Ibrahim and 13 other wanted Indian nationals who have taken refuge in Pakistan.

English daily 'The News', quoting unnamed Pakistan Foreign Office officials, said that India had sought the extradition of 14 of its nationals figuring in the list of 21 given in 2002.

A Foreign Office source, who had examined the names given in the wanted list by India, said the list gave background of some cases going back to 1981.

India is seeking the extradition of its "most wanted man" Dawood Ibrahim, who according to recent US reports lived in Pakistan under a false name and possessed a Pakistani passport, and 13 of its other nationals, it said.

The Indian list also included chief of Jaish-e-Mohammad Maulana Masood Azhar, leader of Lashkar-e-Toiba Hafeez Saeed and leader of Hizbul Mujahideen Sayed Salahuddin.

The daily said Pakistan and India, who are once again in the process of reviewing and updating their old lists of wanted criminals, were likely to exchange the lists after preliminary talks on the issue of extradition entered a crucial phase.

The newspaper quoted a top Government official as saying the extradition treaty with India was being worked out because of the "pressure" from the US Government that wanted Islamabad to co-operate with New Delhi on the issue of extradition of certain wanted men.

Also, in an apparent bid to counter the Indian demand for handing over 21 most wanted persons, Pakistan has told India that it would provide New Delhi with its own list of wanted men, 'The News' daily said.

It said officials in Pakistan Foreign Office while commenting on the Indian list of most wanted men said it was still under the review by the Government. They termed the list as a background material and "not evidence".
