Former President Trump was briefed by intelligence officials about Iran’s alleged assassination threats against him, the Republican presidential nominee’s campaign said on Tuesday.

Confirmation of Tehran's intentions comes a day after intel officials briefed Trump on the alleged plots as payback for US killing an Iranian general.

Along with Russia and China, Iran has also mounted an extensive online influence operation designed to stoke discord and polarization ahead of the November election, intelligence officials have said. Iran also opposes Trump's reelection, seeing him as the candidate more likely to increase tension between Washington and Tehran.
