Andrej Plenkovic said after a meeting of the state crisis committee on Tuesday that about a dozen mostly abandoned houses along the coast have been burnt by the raging fires fueled by strong winds and dry weather.
Plenkovic says the situation has improved after the winds slowed down and planes were able to take off.
Authorities have said that the fires have destroyed hundreds of acres of pine forests, low shrubbery and olive groves along Croatia's coast at the height of the summer tourist season.
The fire caused panic in Split Monday evening after reaching its suburban areas.
As it was reported earlier Ukraine sent firefighting aircraft to put out fire in Montenegro. Thousands of people are evacuated due to forest fires in Montenegro and Croatia.
