BANGKOK (AP) — Authorities say at least four people have been wounded in a blast at an anti-government protest site in Thailand's capital.
The violence is the latest to hit Bangkok as a standoff drags on pitting Prime Minister Yingluck Shinawatra against protesters trying to bring down her government.
The Erawan Medical Center says the injured were taken to four different Bangkok hospitals.
It was not immediately clear what caused the explosion Sunday afternoon.
Late Saturday night, a gunman opened fire on anti-government protesters elsewhere in the capital, severely wounding one man.
And on Friday, an explosive device hurled at a crowd of marching demonstrators killed one and wounded dozens.
It is unclear who is behind the unrest.
