Supporters of Pakistan's Tehrik-e-Insaaf party chant slogans against pro-government leader and chief of Muttahida Quami Movement (MQM) Altaf Hussain in Lahore May 27, 2007 to protest against a ban on their leader Imran Khan for entering the city of Karachi. A southern Pakistani province has barred cricketer-turned politician Khan from visiting for a month after he called the head of a political party a "terrorist" in the wake of deadly gun battles in Karachi earlier this month. The placard reads "We salute the courage of Imran Khan".
