Donald Trump shot at rally

Donald Trump appeared to be shot in the ear as gunshots were fired at him during a rally in Pennsylvania.

Trump clutched the side of his face, and blood splattered across his cheek as several popping sounds echoed.

The former president quickly pumped his fist at the crowd to reassure his supporters he was not severely injured, while Secret Service agents raced to the stage to whisk him away.

This is a developing story.
