BANGKOK — An international rights group accused Thailand's army chief on Thursday of interfering with investigations into deadly political unrest that paralyzed the capital two years ago. New York-based Human Rights Watch issued a statement urging army chief Prayuth Chan-ocha to stay out of the probe into the deaths of more than 90 people killed during a nine-week anti-government protest in Bangkok that ended with a military crackdown. The group accused Prayuth of trying to intimidate investigators and critics in an attempt to halt criticism of the military. “Abuses by soldiers took place in full view of the Thai public and the world's media, yet the Thai army chief is now trying to intimidate investigators and critics into silence,” Brad Adams, Human Rights Watch's Asia director, said in the statement. — AP
