Interim Israeli Prime Minister Ehud Olmert arrived in United States early Sunday for talks with US President George W. Bush ahead of his handover to Barack Obama. "For Ehud Olmert, it is a farewell visit to a close friend and an ally," an Israeli official, who spoke on condition of anonymity, told a foreign news agency before Olmert's departure. "He wants to solidify the promises made to Israel by the Bush administration." During his three-day stay, Olmert hopes to get commitments from Bush on Iran's nuclear programme, after Obama indicated during the election campaign that he might be open to talking with Tehran.
