Myanmar student protesters and nationalists clash with riot police during a march in Letpadan town, some 130 kilometres (80 miles) north of Myanmar's main city on March 10, 2015. Student protesters have embarked on months of demonstrations calling for education reform, but plans by a core group to march to Yangon have been halted by police in the dusty central town of Letpadan, who have surrounded around 150 activists since March 2.
