A stand-off of more than a week between students and police has erupted into violence in Myanmar.<br /><br /> Riot officers lashed out with batons as some 200 students tried to break through blockades and pursue a march in protest at education reforms.<br /><br /> Several people have been detained and injuries are reported.<br /><br /> Trouble flared in the town of Letpadan more than a month after the students had set off on foot from the central city of Mandalay, bound for Yangon, formerly Rangoon.<br /><br /> Police had initially said the march could continue on Tuesday but the agreement fell apart.<br /><br /> Officers chased the students and monks joining them into a Buddhist monastery where they had taken refuge, said a Reuters witness.<br /><br /> The witness saw police using batons to smash the windows of a car belonging to a student and an ambulance where some protesters had taken shelter.<br /><br /> Students claim the reforms will overcentralise education and stifle student unions in the country that is also known as Burma.
