DIYARBAKIR, Turkey (Reuters) - One person died of sunstroke on Thursday as searing temperatures scorched Turkey‘s southeast region. Temperatures in southeastern cities have hit daily highs of more than 40 degrees Celsius (104 Fahrenheit). A 35-year-old waiter died in Kilis, near Turkey‘s border with Syria, after suffering severe sunstroke. Doctors at regional hospitals reported increasing numbers of children with diarrhoea brought on by dehydration from not drinking enough fluids in the warmer weather. The condition can be fatal in the very young. In Sanliurfa, experiencing its hottest summer in 60 years, local restaurants said business had trailed off because residents had lost their appetites. Hospitals in the region have postponed all non-vital operations until September, because the risk of infections is so high, doctors said. Meteorologists said the hot weather looked set for some time with another heatwave coming in from the Gulf next week. Police in Istanbul issued a warning to residents last week to refrain from driving in the heat because of the increased incidence of road rage.
