Republican presidential candidate Donald Trump was briefed on September 24 by U.S. intelligence officials on alleged threats from Iran to assassinate him, Trump's campaign said in a statement. The campaign said intelligence officials have identified that Iranian threats have "heightened in the past few months" and U.S. government officials were working to protect Trump and ensure the elections were not impacted. Iran has previously denied U.S. claims of interfering in American affairs. Iran's permanent mission to the United Nations in New York did not respond to a request for comment late on September 24.
