In Romania, France's ambassador fainted while giving a speech at his embassy.

The country's Health Ministry urged citizens to stay out of the sun between 11 a.m. and 5 p.m.
Dragoljub Djuric, a doctor at a hospital in Bosnia's northern town of Modrica, said its emergency room was overcrowded with people with heat-related problems and that one woman collapsed and died there Thursday.

In Romania, French Ambassador Henri Paul fainted while giving a speech at an embassy reception to celebrate Bastille Day in France. As he fell, he was caught by Romanian Prime Minister Emil Boc.
Paul recovered after drinking a glass of water, and he blamed his collapse on temperatures that reached 35 degrees Celsius (95 degrees Fahrenheit) in Bucharest.
