Ex-Pakistan PM Nawaz Sharif said Indian External Affairs Minister S Jaishankar's Islamabad visit was a "good opening" to break the ice between the neighbouring countries. "Both sides have their grievances. It'll be better if we...bury the past," he said. "We've spent 70 years...(fighting) and we shouldn't let this go on for...next 70 years...We should live like good neighbours," he added.
