Police detain a supporter of Benazir Bhutto during a protest against her detention in her home town of Larkana, 480 km (300 miles) from Karachi November 14, 2007. Pakistani opposition parties tried to forge a united front on Wednesday to end the rule of Pervez Musharraf as the military president insisted a state of emergency he imposed this month was necessary for fair elections.
