ATHENS, Greece (AP) — Wildfires intensified across southern Europe on Wednesday after a nightlong battle to protect the perimeter of Greece’s third-largest city, with at least three more deaths reported in Spain, Turkey and Albania.

Countries such as Spain, Portugal, Italy and Greece have seen highs of more than 40 degrees Celsius in recent days.

High winds were complicating efforts to tame the blazes, which were burning in Greece, Spain, Turkey, Montenegro and Albania.
