Haunting images show 'life jacket graveyard' tribute to refugees outside Parliament
A touching tribute to refugees who died while attempting to cross the Mediterranean has appeared in London's Parliament Square in the form of 2,500 life jackets.
Londoners watched the jackets being laid shortly after dawn, in memory of refugees crossing from Turkey to the Greek island of Chios.
Each of the jackets laid represents a life claimed by the dangerous route traversed by migrant boats in the crossing.
The act coincides with Monday's United Nations summit in New York, aimed at tackling the migrant crisis.
Hundreds of thousands of people have been displaced from their homes across the Middle East as civil war rages in Syria and Iraq, and continued unrest and economic hardship reaches into the north African peninsula.
