Leading Pakistani artistes have joined hands against the government's decision to impose curbs on travelling to India. They say, they have the right to approach the Supreme Court to oppose the order to get a no-objection certificate to visit the neighbouring country.The decision was protested by Samina Ahmed, Madiha Gauhar, Usman Pirzada and other theatre artistes and actors. They said Interior Minister Rehman Malik's announcement was a huge disappointment to all those who are fighting for a liberal and democratic Pakistan. The artists said the move will take Pakistan back to the era of late military ruler Zia-ul-Haq, when such NOCs were the norm.
