Twenty-eight people have been injured, seven of them seriously, in an explosion at a camp of anti-government protesters in the centre of the Thai capital, Bangkok.
Medical officials say the blast happened at the Victory Monument. Reuters reports the incident was the latest violence in more than two months of protests in Bangkok aimed at bringing down the government of Prime Minister, Yingluck Shinawatra.
On Friday night, one protester was killed and 35 wounded when a grenade exploded.
