Temperatures across parts of Europe remain above 40C (104F) , as wildfires rage in Greece.

Winds near Athens have fuelled a major wildfire close to the Greek capital, forcing people from their homes and burning 13.5 square miles (35 square km) of forest and scrubland.

Authorities had declared the huge blaze contained overnight on Wednesday, but firefighters lost control of the fire when the wind picked up, officials said.

Greek Prime Minister Kyriakos Mitsotakis said "the hard times are clearly not over yet", adding: "We are facing another heat wave and a possible strengthening of the winds... absolute vigilance and absolute readiness are required over the next few days."

As well as around Athens, there are also evacuation orders on the island of Rhodes.
