ALEXANDROUPOLIS , Greece — Firefighters on Tuesday found the burnt bodies of 18 people believed to have been migrants who crossed the Turkish border into an area of north-eastern Greece where wildfires have raged for days.

The discovery near the city of Alexandroupolis came as hundreds of firefighters battled dozens of wildfires across the country amid gale-force winds. On Monday, two people died and two firefighters were injured in separate fires in northern and central Greece. Another major blaze has been burning across Tenerife in Spain's Canary Islands for a week, though no injuries or damage to homes was reported.
