If the state does not assume liability for terror attacks, Lufthansa could stop flying, the German air carrier's insurance chief, Ralf Oelssner, said, according to the Financial Times Deutschland newspaper on Wednesday. Airline insurers had cancelled old policies covering terror risks after the Sept. 11, 2001 attacks, resulting in European states temporarily assuming liability for the airlines. They now plan to stop covering certain terror attacks on airplanes or airports starting in 2005. "We don't want to insure these risks anymore; they're incalculable," a spokeswoman for the world's largest re-insurer, Munich Re, told the FTD.
