Lampedusa has seen an influx of migrants with 7,000 people arriving in two days, prompting its mayor and the United Nations refugee agency to warn the Italian island is becoming overwhelmed.

The island – whose population is under 7,000 – has long been a first port of call for people crossing from north Africa and has been a flashpoint in Europe’s migration crisis.

Mayor Filippo Mannino on Thursday said the migrant crisis had reached a “point of no return.”
