Hundreds of firefighters battle a deadly forest fire raging in southern Greece for the third day

Hundreds of firefighters and volunteers in southern Greece battled a wildfire for a third day that has killed two people and devastated a large forested area, prompting pledges of assistance from other European Union countries.

Three waterbombing aircraft from Italy and Croatia were due to arrive later Tuesday after Greece requested help through the 27-country bloc's emergency civil protection mechanism.

The Greek fire service said more than 400 firefighters, assisted by 20 aircraft, were engaged against the blaze in the mountains of Corinthia in the Peloponnese region.

The authorities were optimistic that progress had been made as the main front of the blaze was out, leaving a large number of scattered fires. However, it remained unclear whether that success could be expanded on before winds whipped up and spread the blaze again.
