A mixed martial arts fighter who joined anti-coup protests in Myanmar was wounded by a homemade bomb and later arrested, the military said on Thursday with blasts occurring in at least three cities, Reuters reported.

Phoe Thaw, 36, was arrested in hospital while receiving treatment for leg wounds sustained while testing a home-made bomb late on Wednesday at a Yangon gym, the military’s Myawaddy TV reported.

He was among four people detained and accused of colluding to commit violent acts, it said.
