Israeli Prime Minister Benjamin Netanyahu says he is skeptical that Iran will agree to halt its nuclear program.
Just days ahead of a crucial round of nuclear talks with Tehran, Netanyahu says a diplomatic solution would be the best option but "I see no evidence whatsoever that Iran is ready to end its nuclear program."
The five permanent members of the U.N. Security Council and Germany are gearing up for a May 23 meeting with Iran in Baghdad.
Israel says a nuclear weapon in the hands of Iran would threaten the Jewish state's survival.
Speaking in Prague Friday, Netanyahu called it "the paramount issue of our time."
Netanyahu did not present any ultimatums, but Israeli officials have said time is running out to avoid military action.
