On Sunday, the state-run Myanma Ahlin newspaper put the total of houses burned down in Thandwe last week at 114 houses. It said three religious buildings most likely mosques were destroyed, and 482 people were left homeless.
Thein Sein has been widely praised for overseeing an unprecedented political opening in the Southeast Asian nation since the army ceded power two years ago to a nominally civilian government led by retired military officers.
But rights groups also accuse his government of tolerating, or even abetting, what they describe as ethnic cleansing directed against Muslims in Myanmar, also known as Burma.
They say authorities have done little to crack down on religious intolerance and failed to bridge a divide that has left hundreds of thousands of Muslims marginalized, many of them confined by security forces in inadequately equipped camps after fleeing their homes.
