Two large forest fires, the first of the summer season, were "partly contained" at sundown, a top firefighter told reporters Saturday.
The two fires, one northeast of Athens and one southeast of the city, spread quickly, aided by gale force winds up to 65 kilometers (40 miles) per hour.
By sundown, winds had dropped to about 32 kilometers (20 miles) per hour, but were expected to pick up Sunday morning.
The most serious of the two fires broke out around 1 p.m. local time (1000 GMT) Saturday in a mountain ravine near the coastal resort town of Kalamos, 45 kilometers (28 miles) northeast of Athens. The fire spread southeast, in the direction of the town of Marathon and the nearby Marathon Lake, which serves as a major reservoir for the Greek capital. It stopped well short of both, but threatened five villages along the way. Four of the villages were evacuated.
"The fire is now partly contained. ... It is still expanding in two ravines, one near Kalamos and the other (to the south), but has been contained on other fronts," lieutenant-general Apostolos Gerokostas, deputy head of Greece's fire service, told reporters.
Dozens of fire trucks, 12 planes and 4 helicopters fought the fire. The aircraft cannot operate at night.
A few houses in the area sustained minor damages. No casualties were reported.
"I saw only one building, a guesthouse, completely burned," Gerokostas said.
Another fire had broken out earlier near the port of Lavrio, southeast of Athens, forcing authorities to evacuate a scout camp. Authorities said the fire was under control by sundown.
Forest fires regularly break out in Greece in the summer season, aided by the combination of hot, dry weather and high winds. Huge forest fires devastated a large area east of Athens last year.
