At least six bangs that sound like gunfire are heard while the Republican candidate is on stage - some as he stands behind a podium and after he appears to crouch down behind the podium after the first bang.

Video showed Trump being removed from the site by Secret Service, with his fist raised, after the shots.

It also showed some members of the crowd scatter after initial shots were fired. Others are seen in the video crouching down in stands, some filming the melee with cell phones.

The gunman was killed by Secret Service agents, officials said. One spectator was killed and two others were "critically injured," the Secret Service said.

The ex-president released a statement not long after the shooting:

"I was shot with a bullet that pierced the upper part of my right ear," Trump wrote. "I knew immediately that something was wrong in that i heard a whizzing sound and immediately felt the bullet ripping through the skin."
