A bomb at a Bangkok bus stop has killed one person and wounded at least 10, just as polls closed Sunday in a parliamentary by-election. The vote is being seen as a referendum after recent political unrest.
The bomb was hidden in a rubbish bin in the heart of the commercial district of Ratchaprasong, an area occupied by thousands of "red shirt" anti-government protesters for several weeks until mid-May. Dozens of police and soldiers rushed to the site to search for evidence.
A government spokesman said the blast shows why the government has maintained its state of emergency which is still in place in Bangkok and areas covering a quarter of the country.
The poll is the first electoral test since troops ended the nine-week anti-government protest that drew tens of thousands of supporters and sparked deadly clashes.
