"The two wildfires on Peljesac and the one on Korcula are still burning," Simovic said.
Dubrovnik area voluntary firefighters' chief Ivo Franusic said more than 800 hectares of land on Peljesac had been burned, although houses were not under threat, "but the wind is a problem."
The wildfire on Korcula broke out on Saturday afternoon, while the two on Peljesac broke out on Monday evening.
The fires on Peljesac have destroyed down vineyards, one winery and a think pine forest. Domestic animals have also perished. The residents of Trstenik were temporarily evacuated on Monday evening. Fifty Croatian army members were sent to the peninsula on Tuesday to help put out the flames.
The burned areas on Korcula were visited on Tuesday by Prime Minister Zoran Milanovic, Interior Minister Ranko Ostojic and Defence Minister Ante Kotromanovic.
Milanovic said Croatia had enough manpower and equipment to put out wildfires but underlined the importance of precaution. He would not comment on the possible causes of the fires.
Ostojic said "the police will deal with" the causes. "Now it's important to prevent casualties. The most important thing is that there have been no casualties."
Because of the wildfires on Korcula and Peljesac, Croatian member of the European Parliament Tonino Picula has requested assistance from the European Commission.
