Croatian TV reported that the blaze near the key port and tourist center of Split has reached houses in some parts of the city, with residents joining firefighters in efforts to contain the flames. Authorities warned the residents throughout the town to remain calm, stay indoors, and keep the windows closed as thick smoke spreads through the area. Some parts of Split were left without electricity, Croatian TV said. Soldiers from Croatia joined in the battle to stop the blaze in Montenegro. Croatian Prime Minister Andrej Plenkovic scheduled an emergency meeting for July 18, saying Croatia could seek international help if the crisis continues.
