title: Saudi Crown Prince calls Iran leader 'new Hitler': NYT
text: DUBAI (Reuters) - Saudi Arabia s powerful Crown Prince called the Supreme Leader of Iran  the new Hitler of the Middle East  in an interview with the New York Times published on Thursday, sharply escalating the war of words between the arch-rivals. The Sunni Muslim kingdom of Saudi Arabia and Shi ite Iran back rival sides in wars and political crises throughout the region. Mohammed bin Salman, who is also Saudi defense minister in the U.S.-allied kingdom, suggested the Islamic Republic s alleged expansion under Ayatollah Ali Khamenei needed to be confronted.  But we learned from Europe that appeasement doesn t work. We don t want the new Hitler in Iran to repeat what happened in Europe in the Middle East,  the paper quoted him as saying. Iran reacted harshly by saying that Salman was discredited internationally by his  immature  behavior, state television reported.  No one in the world and in the international arena gives credit to him because of his immature and weak-minded behavior and remarks,  Iran s Foreign Ministry spokesman Bahram Qasemi was quoted as saying.  Now that he has decided to follow the path of famous regional dictators ... he should think about their fate as well.  Tensions soared this month when Lebanon s Saudi-allied Prime Minister Saad Hariri resigned in a television broadcast from Riyadh, citing the influence of Iran-backed Hezbollah in Lebanon and risks to his life. Hezbollah called the move an act of war engineered by Saudi authorities, an accusation they denied.  Hariri has since suspended his resignation. Saudi Arabia has launched thousands of air strikes in a 2-1/2-year-old war in neighboring Yemen to defeat the Iranian-aligned Houthi movement that seized broad swaths of the country. Salman told the Times that the war was going in its favor and that its allies controlled 85 percent of Yemen s territory. The Houthis, however, still retain the main population centers despite the war effort by a Saudi-led military coalition which receives intelligence and refueling for its warplanes by the United States. Some 10,000 people have died in the conflict. The group launched a ballistic missile toward Riyadh s main airport on Nov. 4, which Saudi Arabis decried as an act of war by Tehran. Bin Salman said in May that the kingdom would make sure any future struggle between the two countries  is waged in Iran . For his part, Khamenei has referred to the House of Saud as an  accursed tree , and Iranian officials have accused the kingdom of spreading terrorism, an accusation it denies.
