In that case, we will take further measures to protect the US consulate.”Foreign Minister Hina Rabbani Khar criticised the film.“We have always promoted inter-faith harmony but desecration of any type is always condemned by Pakistan and we are very, very strongly condemning,” she said when asked about her government’s reaction to the disputed film.In Peshawar, authorities said they were “cautious” about the developing situation.The patrolling of police around the consulate in Karachi was also stepped up.
