Thailand's Election Commission on Thursday urged the government to delay polls scheduled for February as clashes between police and anti-government protesters killed at least one person and injured dozens, AP reported. A police officer was killed in the hours-long unrest outside a Bangkok sports stadium where election candidates were gathering to draw lots for their positions on the ballots. Protesters threw rocks as they tried to break into the building to halt the process, while police fired tear gas and rubber bullets. Four election commissioners left the stadium on a helicopter to escape the turmoil, according to a spokesman for the body. Prime Minister Yingluck Shinawatra has been insisting the elections should go ahead, in the knowledge that her party is likely win.
