Pakistan on Friday confirmed a surprise visit by Indian Prime Minister Narendra Modi to the eastern city of Lahore where he would meet his Pakistani counterpart Nawaz Sharif. 

"I can confirm that Indian Prime Minister Narendra Modi is arriving in Lahore," Pakistani foreign ministry spokesman Qazi Khalilullah told state television.

"The details of the meeting are being worked out," he added.

Modi and Sharif have had a stop-start diplomatic relationship since the Indian premier's surprise invite to Sharif for his inauguration last May.
