Government officials said on Friday that lower temperatures and higher humidity overnight were helping ease pressures on beleaguered fire squads, who turned their attention to forests and undergrowth along dunes of fine sand. Europe is facing an extremely hot summer, fuelling wildfires from the Atlantic coast to the eastern Mediterranean. More than 100 firefighters have been deployed to battle the blaze, which has now burned about 150 hectares, in Dunwich Heath.
