Trump rally shooting: How it unfolded in pictures

A series of shots rang out during Donald Trump's presidential campaign rally in Butler, Pennsylvania. Secret Service agents quickly ran onto the stage and surrounded Trump, who dropped down at the podium.

The moment a series of shots rang out, Donald Trump could be seen touching his right ear. Then Secret Service agents rushed to the stage and pulled down the former president. They huddled over him while other security officials secured the venue.

After surrounding Trump, Secret Service agents helped the former president to his feet. Streaks of blood could be seen smeared across his face. Trump pumped his fist towards the crowd, mouthing "fight, fight, fight." Many in the crowd chanted, "USA, USA."

After Secret Service agents helped Trump to his feet, the former president raised his fist in the air in a defiant gesture. While blood was streaked on his face, he could be seen telling the crowd to "fight, fight". Images of the moment, captured here by AP photographer Evan Vucci, quickly circulated on social media as many Republicans saw it as a defining moment of the Trump election.

Trump had just started his speech at an outdoor campaign when the shots rang out. He had been talking about migrants. One eyewitness told the Reuters news agency that, at first, it sounded like fireworks, but then people began screaming. "Everyone started panicking. It was chaos," he said.

One person in the crowd was killed, and two were seriously injured, security officials said. A doctor in the crowd rushed to aid one of the injured. Speaking to reporters afterword, the doctor said the person had been shot in the head. The death was later confirmed.

The news of what the FBI said was an "assassination attempt" made headlines around the world. In the US, President Joe Biden said he was relieved Trump was safe. He condemned the attack, "There's no place in America for this kind of violence." Vice President Kamals Harris, who was also campaigning in Pennsylvania, condemned the "abhorrent act."

US President Joe Biden returned to Washington from his beach house in Delaware and also spoke with Donald Trump after he was released from the hospital. Biden said he was grateful to the Secret Service for getting Trump to safety. Referring to the attack, he wrote on Twitter, "It's sick. It's sick. It's one of the reasons why we have to unite this country."

Police officers from Rehoboth Beach in Delaware guard the town hall where US President Joe Biden gave a speech condemning the attack on his likely rival in upcoming presidential elections.

Several hours after the shooting, the FBI took over the lead in the investigation. The FBI has since confirmed an "assassination attempt" on Trump and that they had identified the shooter. Special Agent Kevin Rojek said officials were "working feverishly" on the case. The FBI said it had "no reason" to believe that a further threat existed.

Police in New York City stood guard in front of Trump Tower in Midtown Manhattan. After he left the hospital, Donald Trump was expected to spend the night at his home in New Jersey, The New York Times reported.

Members of the Secret Service patrolled the grounds in Pennsylvania where Donald Trump had earlier been shot. The attack was the most serious attempt to assassinate a president or presidential candidate since 1981, when Ronald Reagan was shot.
