A 70-year-old Buddhist monk was hacked to death by unidentified miscreants inside a monastery in southeast Bangladesh, a week after a Muslim Sufi preacher was murdered in a similar attack.

Mawng Shoi Wuu, chief of the monastery located in the Chittagong Hill Tracts district of Bandarban's Naikhyongchari Upazila, was found dead in this morning by a worker, police said.

Assailants slit his throat sometime last night, they said.

The latest assault bears the hallmark of previous murders of intellectuals, bloggers and minorities by Islamists in the country.

Last week, a 65-year-old Muslim Sufi preacher was hacked to death by unidentified machete-wielding assailants in northwest Bangladesh's Rajshahi city.
