A week-long wildfire on the Greek island of Rhodes has forcing large evacuations, while three major fires rage elsewhere in the country, fueled by strong winds and successive heat waves.

These latest evacuations were ordered in south Rhodes Sunday, seeing some 19,000 people, mostly tourists, moved in buses and boats over the weekend out of the path of the blazes that reached several coastal areas from nearby mountains.

Further evacuations took place overnight on the islands of Corfu and Evia and on the southern mainland.

The Ministry of Climate Change and Civil Protection called it the largest evacuation ever from a wildfire in the country.

Rhodes is a very popular destination for British tourists, and Britain’s ambassador to Greece has announced the U.K. government is sending a rapid deployment team to support British nationals.

Heat wave conditions are expected to persist in Greece through Thursday.
