DUBAI( Reuters)-A young man was shot dead during a second night of protests over water shortages in southwest Iran, a local official said on Saturday, blaming armed protesters for the shooting, the state news agency IRNA reported. Iran is facing its worst drought in 50 years, with protests breaking out in several cities and towns in the oil-rich Khuzestan province over the water crisis, which has affected households, devastated agriculture and livestock farming and led to power blackouts."
