LONDON, ENGLAND - MARCH 13:  Milie, aged 9, releases a red, heart-shaped balloon in Parliament Square in front of the Houses of Parliament as a symbolic marking of the third anniversary of the Syrian conflict on March 13, 2014 in London, England. The image of a girl releasing a red balloon recreates the famous 'There Is Always Hope' graffiti on London's South Bank by Banksy. The 3rd anniversary of the Syrian crisis is due to be marked by the simultaneous release of red balloons in New York, Washington DC, Moscow, Paris and the largest Syrian refugee camp in Jordan, Za'atari Camp.
