Dozens Hurt In Thailand Grenade Attacks
Witnesses say there were two explosions close to a stage set up by anti-Government protesters.
At least 28 people were injured, seven seriously.
Demonstrators are attempting to displace Prime Minister Yingluck Shinawatra and her self-exiled brother Thaksin.
Mr Shinawatra has lived abroad since 2008 to avoid a prison sentence after being convicted of corruption.
They are trying to overthrow the government and stop the upcoming elections in February.
