(Reuters) - Myanmar declared martial law in four central townships on Friday after unrest between Buddhists and Muslims stoked fears that last year's sectarian bloodshed was spreading into the country's heartland in a test of Asia's newest democracy.
Whole neighborhoods were still smoldering on Friday and agitated Buddhist crowds roamed the streets after three days of turbulence, said Reuters reporters in the city 540 km (336 miles) north of the commercial capital Yangon.
Twenty people, including a Buddhist monk, have been killed and dozens wounded since Wednesday, said Win Htein, a lawmaker for the opposition National League for Democracy (NLD) party.
Two camps now held more than 2,000 people displaced by the fighting, he added.
The unleashing of ethnic hatred, suppressed during 49 years of military rule that ended in March 2011, is challenging the reformist government of one of Asia's most ethnically diverse countries.
Jailed dissidents have been released, a free election held and censorship lifted in Myanmar's historic democratic transition. But the government has faced mounting criticism over its failure to stop the bloodshed between Buddhists and Muslims.
"I am really sad over what happened here because this is not just happening to one person. It's affecting all of us," said Maung Maung, a Buddhist official in Meikhtila.
Hundreds of Muslims have fled their homes to shelter at a sports stadium, local officials said.
