A bomb has exploded at a bus stop in the Thai capital, Bangkok, killing one person and wounding 10 others.
The blast occurred in an area occupied by “red-shirt” anti-government protesters for weeks until a crackdown by the security forces in May.
It came as voting ended in a closely-watched by-election in the city.
Unofficial results suggest the government’s candidate has defeated a leader of the protesters, who was running from his prison cell.
Panich Vikitsreth of the Democrat Party, Thailand’s vice-minister for foreign affairs, was said to have won about 54% of the vote in the contest for a vacant seat in the House of Representatives.
