Romania ? Southern Europe sizzled under a heat wave Tuesday, with temperatures hitting triple digits for a seventh day in Romania, blazes forcing the evacuation of tourists in Croatia and Italy, and wildfires in Macedonia and Greece exploding shells from long-ago wars. At least 35 heat-related deaths were reported.

Romanian authorities warned residents to stay indoors during the midday heat in the capital of Bucharest, one of five countries put on high alert because of the weather.

At least 27 people have died in Romania since last week, with 12 deaths reported Monday, said Health Minister Eugen Nicolaescu. The victims, all over 70, collapsed in the street and had not taken precautions, such as wearing a hat, he said.

As temperatures in Bucharest hit 105 Tuesday, heavy use of air conditioning caused power outages in the city, and Finance Minister Varujan Vosganian said energy consumption had surged by more than 50 percent.
