Iranian authorities have urged residents to limit water consumption as the country grapples with severe shortages amid an ongoing heatwave, according to local media. Water scarcity is a major issue in Iran, particularly in arid provinces in the country's south, with shortages blamed on mismanagement and overexploitation of underground resources as well as the growing impact of climate change.
