Former US President Donald Trump has been rushed from a stage with blood on his face after a shooting at a campaign rally in Pennsylvania.
Two people, including the suspected shooter, have been confirmed dead following the incident, which is being investigated as an attempted assassination of the former president and presumptive Republican nominee.
Here is what we know so far.
What happened?
Trump was showing off a chart of border crossing numbers during a rally attended by about 50,000 people before the Republican National Convention about 6.10pm on Saturday (local time) when shots began.
As Trump was talking, a popping sound was heard, and the former president put his right hand up to his right ear, as people in the stands behind him appeared to be shocked.
How the shooting attack on Donald Trump unfolded
As the first pop rang out, Trump said, "Oh," and grabbed his ear as two more pops could be heard and he crouched down. More shots are heard then.
Someone could be heard saying near the microphone at Trump's lectern, "Get down, get down, get down, get down!" as agents tackled the former president.
They piled atop him to shield him with their bodies, as other agents took up positions on stage to search for the threat.
Screams were heard in the crowd of several thousand people.
Afterward, voices were heard saying "shooter's down" several times, before someone asked, "Are we good to move?" and "Are we clear?" Then, someone orders "Let's move."
He could be heard on the video saying at least twice, "Let me get my shoes, let me get my shoes," with another voice heard saying, "I've got you, Sir."
Trump got to his feet moments later and could be seen reaching with his right hand toward his face. There appeared to be blood on his face.
He then pumped his fist in the air and appeared to mouth the word "Fight" twice his crowd of supporters, prompting loud cheers and then chants of "USA. USA. USA."
The crowd cheered as he got back up and pumped his fist.
His motorcade left the venue moments later. Video showed Trump turning back to the crowd and raising a fist right before he is put into a vehicle.
Police began vacating the fairgrounds shortly after Trump left the stage in what local officers described as a crime scene.
What is Donald Trump's condition?
Blood was seen appearing to come from Trump's ear.
About 2.5 hours after the attack, Trump has posted a message on his Truth Social account revealing he was shot by a bullet that pierced the upper part of his right ear.
"I was shot with a bullet that pierced the upper part of my right ear. I knew immediately that something was wrong in that I heard a whizzing sound, shots, and immediately felt the bullet ripping through the skin. Much bleeding took place, so I realized then what was happening. GOD BLESS AMERICA!" he wrote.
Trump thanked the Secret Service and all law enforcement for their rapid response.
"Most importantly, I want to extend my condolences to the family of the person at the Rally who was killed, and also to the family of another person that was badly injured."
"It is incredible that such an act can take place in our Country. Nothing is known at this time about the shooter, who is now dead," he wrote.
A spokesman for Trump, Steven Cheung, earlier released a statement saying the former president was "fine".
"President Trump thanks law enforcement and first responders for their quick action during this heinous act," the statement reads.
"He is fine and is being checked out at a local medical facility. More details will follow."
Who fired the shots?
Not many details are known about the shooter yet, who was killed by Secret Service agents, but he was not an attendee at the rally
Butler County District Attorney Richard Goldinger said the shooter was outside the rally grounds, but he didn't give additional information about where.
"Quite frankly I don't know how he would have gotten to the location where he was, but he was outside the grounds, and I think that's something that we're going to have to figure out — how he got there," he said,
Who has died?
Goldinger said the suspected gunman was dead and at least one rally attendee was killed.
He said that in addition to the spectator who was killed, another attendee was taken to a local hospital and in serious condition.
