Mati: At least 20 people died and more than 100 were injured on Monday as a wildfire swept through a small resort town in eastern Greece with many victims trapped by flames as they fled.

The fire in Mati village, some 29 km east of Athens, was by far the country's worst since blazes devastated the southern Peloponnese peninsula in August 2007, killing dozens. Monday's fire was one of several that broke out in the country amid a sweltering heat wave.

"Mati doesn't even exist as a settlement anymore," one woman told Greece's Skai TV. "I saw corpses, burned-out cars. I feel lucky to be alive."

Mati is in the Rafina region which is popular with local tourists, particularly pensioners and children at holiday camps.
