Iran claims US preparing to bomb again as Trump threatens to 'wipe Iran out'

Middle East governments are preparing for more violence. Iran says it has intelligence that the US is planning a new bombing campaign against it. Tensions are rising before this week's UN General Assembly in New York. On Sunday, Donald Trump ended a weekend visit to the Camp David presidential retreat early. No official reason was given. The US State Department also issued a new security alert to all US citizens in the Middle East. The moves follow attacks on Riyadh by Houthi rebels and Trump's comment to Fox News that he is considering "wiping Iran out."
