Seven people have been killed and 12 injured by Myanmar police when it opened fire on demonstrators with live bullets in Rakhine State. It was not immediately clear why the rally descended into violence. The clashes also came on the same day as a repatriation agreement was signed between Myanmar and Bangladesh to start the return of some 655,000 Muslim Rohingya refugees from squalid camps back over the border. Communal tension between the Buddhist Rakhine population and Muslim Rohingya has risen sharply in recent years. Many Rakhine Buddhists joined the attacks on Rohingya villages, and their leaders are adamant that they will not accept the refugees back from Bangladesh.
