ATHENS, Greece — A massive wildfire that destroyed vast tracts of forest in northeastern Greece over 17 days was in abeyance on Monday, although hundreds of firefighters were still tackling pockets that continued to burn, the fire department said. Authorities also warned that parts of the country were at risk of flooding due to heavy rainstorms forecast overnight and on Tuesday that could pose a particular threat to fire-ravaged areas. Reinforcements were sent over the weekend to battle the wildfire burning in the Evros region near the border with Turkey, bringing the total number of firefighters on Monday to 741, backed by 124 vehicles and two aircraft. …The fire, which broke out on Aug. 19 near the northeastern city of Alexandroupolis and joined with other blazes to form one massive wildfire, burned more than 93,000 hectares (230,000 acres) of land by Sunday, making it the largest single blaze to hit an EU country since records began in 2000.
