Romania has declared a 'Code Red' emergency as the death toll from a week-long heatwave climbed to 18.
Romanian Health Minister Eugen Nicolaescu said three Romanians had died in the last 24 hours and urged people to cancel outdoor travel in the hottest part of the day.
Meteorologists have forecast three days of rising temperatures in the region's second heat wave this year.
In June, more than 35 people died in Romania, Turkey and Greece when the temperature reached 46C.
In Greece, officials called a state of emergency, forecasting temperatures of 45C.
Health services said 13 people had been rushed to hospital with heat-related symptoms and an emergency plan has been activated.
