NEW DELHI (AP) — India says it has called off talks with Pakistan after its ambassador met with Kashmiri separatists.

External Affairs Ministry spokesman Syed Akbaruddin said Monday that the Pakistani high commissioner’s meeting with the separatists had undermined efforts to improve often-hostile ties.

India and Pakistan agreed to resume talks on improved relations in May when Pakistan Prime Minister Nawaz Sharif attended the inauguration of Indian Prime Minister Narendra Modi.

The two countries’ foreign secretaries were to meet next week to discuss the resumption of a formal dialogue.

About a dozen Islamic groups have been fighting for the independence of the Indian-controlled portion of Kashmir, or its merger with Pakistan.

India accuses Pakistan of arming and financing the militants. Islamabad denies the charge and says it only gives them moral and diplomatic support.
