There have been a series of explosions in the Thai capital Bangkok. At least one person has died and 75 are injured. According to an army spokesman the blasts were caused by grenades, but it is not clear who launched them.
The area hit is the business district of the city, where a number of offices, banks and hotels are located. There have been hundreds of heavily armed soldiers in the region since Monday. Ranged against them are thousands of anti-government protesters.
The red-shirts – supporters of former Prime Minister Thaksin Shinawatra – have barricaded themselves into the area.
Almost two weeks ago the army tried to forcibly disperse the protesters but this move resulted in 25 deaths and 800 wounded.
