Former US President Donald Trump was attacked on Saturday at a campaign rally when he was shot multiple times in Butler Town, Pennsylvania.
Trump suffered an ear injury but is reported to be safe.
The incident took place two days before his nomination as presidential candidate by the Republican National Convention.
The recent attack on Trump reflects the long history of assassination attempts against previous US presidents and presidential candidates.
Let's take a brief look at the American presidents who are under attack:
Andrew Jackson — 1835
The seventh president of the United States, Andrew Jackson, was attacked in 1835 by Richard Lawrence outside the Capitol, but his two pistols misfired. This made him the first person to attempt to assassinate a US president.
Abraham Lincoln — 1865
In 1865, Abraham Lincoln was assassinated by John Wikes Booth while attending a performance at Ford's Theatre in Washington, DC.
He previously escaped an assassination attempt in 1864.
James A. Garfield — 1881
Charles Guiteau, a failed candidate for public office, attacked James A. Garfield twice in 1881 at a Washington, D.C., train station. The 20th President of the United States was so severely injured that he suffered for months and died in 1881.
William McKinley — 1901
William McKinley was shot twice by an anarchist named Leon Czolgosz during a public event in Buffalo, New York, in 1901.
