Migrants in Calais torch tents and shelters in a last act of defiance as French authorities clear the squalid camp that once housed more than 6,000 people. Fires are raging across parts of the “Jungle” migrant camp in Calais, three days into a French operation to demolish it. It was unclear who set the dozens of fires overnight and in the morning. The clearance began on Monday and about 4,000 migrants – out of some 7,000 – have been taken from the squalid camp to shelters around France. The prefect of Pas-de-Calais said authorities now expected to finish the evacuation operation on Wednesday. The camp has become a key symbol of Europe’s migration crisis, with its residents desperate to reach the UK.
