Sandbags

British army soldiers place sandbags at the entrance to a flooded house at Chertsey, England, Wednesday, Feb. 12, 2014.  The River Thames has burst its banks after reaching its highest level for many years, flooding riverside towns upstream of London, including Chertsey which is about 30 miles west of central London. Some hundreds of troops have been deployed to assist with flood protection and to get medical assistance to the sick and vulnerable.
