Hundreds of firefighters battled a deadly wildfire near Athens for a second day on Saturday, with strong winds raising fears it could spread.

A fire department spokesman said more than 260 firefighters with nearly 80 fire engines and 12 aircraft were deployed near Keratea, a rural area some 27 miles southeast of Athens.

'The fire has weakened but there are still active pockets,' the spokesman told AFP.

A new fire broke out close to the nearby town of Kouvaras on Saturday but was quickly brought under control.

Dimitris Loukas, mayor of the nearest city of Lavrio, said the Keratea fire that broke out Friday had devastated nearly 10,000 acres of brush and forest.
