Islamabad- Advisor to Prime Minister on National Security and Foreign Affairs Sartaj Aziz has urged protesting parties to resolve the political issues through dialogue today. Talking to newsmen in Islamabad, he said the protesters should adopt positive attitude to find an amicable solution to the problems instead of continuing their protests at roads. He said the country is suffering a lot due to the politics of sit-ins. Sartaj Aziz condemned irresponsible statement of Imran Khan about not paying the utilities bills and taxes. "It is important to remind everybody that they, too, have taken casualties in that fight, so it's a common threat. We don't always see eye-to-eye on how to address it. That remains to be the case today. "But what's different today is that we have better vehicles for dialogue and cooperation with the Pakistani military that we continue to enjoy and want to and continue to improve," he said.
