One person has been arrested and an assault rifle recovered after “an apparent assassination attempt” on Donald Trump, according to the FBI.
Mr Trump was playing a round at Trump International Golf Course in West Palm Beach when gunshots were heard.
Palm Beach County Sheriff Ric Bradshaw told reporters that a Secret Service agent – who was patrolling the course ahead of Mr Trump – spotted a rifle barrel coming out of a perimeter fence.
“He immediately engaged that individual, at which time the individual took off,” he said.
It is not yet known whether the suspect fired first or fired a round at all or if only the Secret Service fired.

Secret Service move Trump to safety after shots heard
A witness spotted the man fleeing the scene in a black Nissan and managed to take photos of the car and number plate.
Authorities then sent out an alert to statewide agencies with the information on the vehicle.
Officers later searched the area where the man was spotted and found an AK-47-style rifle with a scope, two rucksacks and a GoPro.
Earlier Martin County Sheriff William Snyder described how his officers followed the suspect vehicle for a while before making a “felony stop”.
“Our road units picked the vehicle up and we waited a while. We didn’t stop him right away. We didn’t want a high-speed chase.
“So we were able to wait until we had adequate units, surrounded the vehicle, and forced it to a stop.”
He added they managed to take the suspect into custody peacefully.

What we know about what happened so far
One person is currently being questioned by local police.
Afterwards, a statement from Mr Trump said: “There were gunshots in my vicinity, but before rumors start spiraling out of control, I wanted you to hear this first: I AM SAFE AND WELL!
“Nothing will slow me down. I will NEVER SURRENDER! I will always love you for supporting me.
“Unity. Peace. Make America Great Again. May God bless you.”
Mr Trump has since returned to his Mar-a-Lago resort.
A White House statement said: “The President and Vice President have been briefed about the security incident at the Trump International Golf Course, where former President Trump was golfing.
“They are relieved to know that he is safe. They will be kept regularly updated by their team.”
It comes two months after the Republican presidential nominee was shot during an assassination attempt at a rally in Pennsylvania.
