BANGKOK, THAILAND - MAY 23: Hundreds of Bangkok residents participate in a Bangkok Clean Up day sweeping up the streets with soap and water May 23, 2010 in Bangkok, Thailand. A reduced night-time curfew remains in place in Bangkok to prevent a resurgence of unrest. At least 86 people have been killed in clashes with military forces since mid-March when the political turmoil took hold. Bangkok experienced its worst political violence in decades during the Red Shirt occupation ending with the military crackdown on the camp causing the redshirts to take revenge setting fire to buildings, including the country's stock exchange and biggest shopping mall, the CentralWorld.
