Temperatures climbed as high as 43 Celsius (109 Fahrenheit) in parts of Greece yesterday with cooler weather not expected until Thursday, according to meteorologists.

Temperatures in the southern city of Kalamata hit 43C (109F), while in Athens the thermometer rose to 41C (106F).

Press reports said that seven people were taken to hospital with heat-related problems.

The country’s power grid coped with the extra demand but brief blackouts were reported in parts of Athens, including Faliron and Kallithea. Other areas of Greece were left without power for short periods.

Experts said the power system of the Public Power Corporation (PPC) will come under greater strain today due to the start of the working week and higher demand for electricity on account of air conditioners.
