Gunshots, panic and then fury BBC correspondent's account of ...

Sometimes sounds can be deceptive. A car backfiring can make you jump; a firework can make you flinch; but as soon as we heard the gunfire at the Butler Farm showgrounds shortly after 6pm on Saturday evening, we all knew straight away that these were gunshots, and there were lots of them.

Donald Trump was mid-way through a sentence as the shots rang out. He grabbed his ear before dropping to the ground and being smothered by Secret Service agents.

We didn’t know it at the time, but the gunman was perhaps 150m away from where we stood, lying flat on the roof of a shed and firing at least six rounds using an AR-15 rifle at the former president and terrifed spectators.

I was about to go on air, with radio colleagues from the BBC World Service waiting on the end of a line. Instead all three of us in my team - me, producer Iona Hampson and cameraman Sam Beattie - went to the ground, using our car as some kind of shelter, the only shelter we had.

We had no idea where the shooting was coming from; how many shooters there were; and how long it would go on for. Frankly it was terrifying.

As we lay on the ground, Sam turned on his camera and I tried to give my first impressions of what was happening. In that moment, we had no more concrete information than that about six minutes into Donald Trump’s speech, the shooting had begun.
