Photo taken with drone on Aug. 5, 2018 shows a sign of a word "EIRE" which stands for Ireland in Irish and a number of eight on a burned hill in Bray, a town some 40 km south of Dublin, Ireland. The sign, built with stones during the World War II for navigating and alerting pilots, was revealed on Saturday after the hill caught a wildfire due to a recent heatwave in Ireland. (Xinhua)
