Five truckloads of soldiers were seen heading downtown in Myanmar's largest city Tuesday soon after tens of thousands of people led by Buddhist monks defied orders to stay off the streets and marched in another peaceful anti-government protest.Monks have taken over leadership of anti-government protests that began over a month ago, leading marches for the past eight days that are the largest anti-government protests since a 1988 pro-democracy uprising was brutally suppressed by the military.
