Greece is struggling to contain four major wildfires within its borders as firefighters are stretched thin and homes are evacuated.

The newest fire began Saturday morning on the island of Lesbos, forcing local authorities to evacuate hundreds from homes and an exclusive resort. Authorities relocated 450 people for that fire alone, while three others continue to burn on the Grecian mainland.

Roughly 50 firefighters, 17 fire engines and nine fire-fighting aircraft were combating the blaze as of Saturday, fire service spokesman Yannis Artopoios told reporters.

The remaining fires are in Western Macedonia, the Southern Peloponnese region, and in the northeast Dadia national forest near the Greece-Turkey border.
