The Thai military says security forces plan to surround a protest march in Bangkok with armoured vehicles. A spokesman said that routes into the sprawling encampment would be closed today. He said protesters would be free to leave but not enter. The move comes a day after the government announced and then cancelled a plan to cut-off water and power supplies to the protesters. The group has been occupying key parts of the capital since 14 March. They want Prime Minister Abhisit Vejjajiva to dissolve Parliament and call fresh elections. He had offered polls on 14 November, but the two sides failed to agree a deal.
