A Myanmar doctor who criticised conservative Buddhist monks has been charged with insulting religion, officials said on Thursday, as a debate heats up over a proposal to teach sex education at school, according to a Reuters report.

Kyaw Win Thant, 31, was arrested after angry scenes at a monastery in Meiktila, where he apologised to monks for deriding them in Facebook posts. His attacks stemmed from comments posted by numerous other monks denouncing the government’s proposal.

Several sources confirmed on Thursday that Kyaw Win Thant had been charged with insulting a religion or religious beliefs, the Reuters report said.
