Former US President Donald Trump was rushed off stage after gunshots erupted at a rally in Pennsylvania in an apparent assassination attempt.
Footage showed him grimace and raise a hand to his right ear, before ducking as several sharp cracks - a series of shots - broke out.
He was quickly swarmed by US Secret Service agents and dragged off stage to a waiting vehicle. He raised a fist as he was bundled into the car.
In a post to his Truth Social network, Trump said a bullet pierced the "upper part" of his right ear. Earlier, his spokesperson said he was receiving treatment at a local medical centre.
"I knew immediately that something was wrong in that I heard a whizzing sound, shots, and immediately felt the bullet ripping through the skin," Trump wrote. "Much bleeding took place, so I realized then what was happening."
Blood was clearly visible on Trump's ear and face as protection officers rushed him away.
The suspect was shot dead at the scene by US Secret Service officers, the agency's spokesperson Anthony Guglielmi said. He added that one bystander was killed in the shooting and two others were critically injured.
The attack was the first attempt to assassinate a president or presidential candidate since Ronald Reagan was shot in 1981.
