India said Friday it has urged Pakistan against meeting Kashmir separatist leaders ahead of a rare weekend talks between the two countries top security advisers in New Delhi, hiking tensions between the arch rivals. The foreign ministry said it would be inappropriate for Pakistan National Security Adviser Sartaj Aziz to hold the meeting on Sunday in Delhi just before scheduled talks with his Indian counterpart Ajit Doval. “India has advised Pakistan yesterday that it would not be appropriate for Mr Sartaj Aziz to meet the Hurriyat (separatists) representatives in India,” foreign ministry spokesman Vikas Swarup said on Twitter. “Such a meeting would not be in keeping with the spirit and intent of the Ufa understanding to jointly work to combat terrorism.” Indian President Narendra Modi met Pakistani counterpart Nawaz Sharif during a visit to the Russian city of Ufa last month, with the hour long talks seen as a new thaw in ties between the countries. About a dozen militant groups have been fighting since 1989 for either the independence of the Indian controlled portion of Kashmir or its merger with Pakistan.
