TOPSHOTS A dinghy carrying migrants crosses the Aegean sea between Turkey and Greece off the Greek island of Kos on August 13, 2015. Greece sent extra riot police to Kos as tensions mounted over a huge influx of migrants. The Greek government said it was "immediately" dispatching a ship to Kos to double up as an accommodation and processing centre for up to 2,500 people as around 7,000 migrants wait to apply for immigration papers.
