YANGON, Burma (AP) — The chief minister of Burma’s Rakhine state that has been embroiled in sectarian violence has retired and the country’s religious affairs minister has been fired.

An announcement signed by President Thein Sein gave no explanation for Hla Maung Tin’s retirement or for the sacking of Hsan Sint.

Several official sources said Hsan Sint is facing an investigation on corruption charges. His removal coincides with the arrest of five Buddhist monks last week after a well-known Buddhist monastery was raided in a late-night operation. The sources would not give their names are they were not authorized to speak to the media.

Rakhine has been caught up in sectarian violence since mid-2012 that has challenged the government and brought international criticism.

The moves come after the education minister retired two days ago.
