JUST IN: Pakistan PM Nawaz Sharif says he is ready to hold talks with India.

So far, India has ruled out a formal meeting with Pakistan at the SAARC summit. The two-days SAARC summit begins tomorrow in Kathmandu, Nepal.

Earlier in the day, external affairs minister Sushma Swaraj met her Pakistani counterpart Sartaj Aziz on the sidelines of the SAARC summit. She termed the meeting a "courtesy'. The ministers had a brief exchange of words as they passed each other during the summit.

"It is basic courtesy. If you meet ministers of other countries on an international platform, you greet each other,' she said while talking to reporters.

The brief interaction between the two ministers took place even as speculations are being made regarding a possible informal meeting between Indian Prime Minister Narendra Modi and Pakistan PM Nawaz Sharif. However, both Swaraj and Aziz refused to comment about any possible meeting between the two leaders.
