Moment 400 people gathered with mirrors on the south coast to reflect SOS signal to Europe

This is the moment more than 400 people gathered on cliffs at the south coast and used mirrors to flash an SOS signal to Europe.

The art installation saw people stand in a huge long line on the cliffs at Saltdean near Brighton on Saturday. Armed with mirrors of all sizes, they reflected the sun's rays, flashing out a "symbolic SOS call".
