The former Croatian prime minister Ivo Sanader was urgently brought back from a vacation cruise and hospitalized with pneumonia, the national television HTV reported Friday. Sanader, 56, was initially hustled to an infective clinic, but after he was determined to have a strong lung infection he was transferred to a general hospital. He was under a strong antibiotic therapy, reports said. He stunningly resigned from the government and as the head of the conservative Croatian Democratic Union on July 1, effectively without explaining his move and fuelling speculation, among else about his health. "Thank God, I'm healthy," he said then. After Jadranka Kosor took over from him in the party and the cabinet, Sanader departed for a cruise vacation along the Croatian coast on a private yacht. At the time he interrupted the cruise, his ship was sailing off Split, 300 kilometres southwest of Zagreb.
