Firefighters in Greece on Tuesday were hoping to contain a wildfire on the outskirts of Athens burning for a fifth day, with winds that had restricted the use of water-bombing aircraft finally subsiding. Over 500 firefighters were deployed in villages around Mount Kithairon, some 60 kilometres (37 miles) northwest of the capital according to the fire service. At Porto Germeno on Tuesday, police had set up cordons to check people wishing to visit the area, where damage evaluation is ongoing. On Sunday, two Bell helicopters collided while operating on the western outskirts of Athens, killing a Danish pilot and his Greek co-pilot. Police have made two arrests over the Porto Germeno fire, believed to have started from a faulty power cable, including a local mayor.
