More than 200 students defied the government Thursday, marching in driving rain across northwest Beijing for a fourth day of pro-democracy protests despite an official ban on demonstrations.

The students from Beijing Teaching University said they expected to meet up with some 500 students from Beijing University and march together to Tiananmen Square and the Communist Party headquarters.They said they would not respect an order issued by the Beijing city government earlier Thursday aimed at quelling the wave of unrest in the Chinese capital.
