America has a long history of campus shootings with the attacks at the Christian Oikos University in California the latest.

One L Goh, a 43-year-old former nursing student at the Oakland institution, is alleged to have shot dead seven people and injured three others.

But the trend of school and university killings stretches back decades.

In 1966, student Charles Whitman turned his rifle on the campus of the University of Texas at Austin, killing 16 and injuring more than 30 in a rampage which went on for more than 90-minutes.

In 1991, Gang Lu, opened fire on two buildings at the University of Iowa campus.

The graduate student from China was apparently upset because he had been passed over for an academic honour. The 28-year old from China killed 5 people before turning the gun on himself.

While defending his thesis before a faculty committee in 1996, 36-year old Frederick Martin Davidson produced a handgun. He killed three professors at San Diego State University.

Columbine High School has become one of the most infamous campus killing sprees. Two boys killed 12 students and a teacher in 1996 at the school in Colorado, before ending their own lives.

At the University of Arkansas in 2000 James Easton Kelly, 36, who had been recently dropped from a doctoral programme and the professor overseeing his work John Locke, 67, were shot in an apparent murder-suicide.

In 2002, Robert Flores, a failing nursing student at the University of Arizona, killed a female instructor in her office. The 40-year old Gulf War veteran went on to kill two more instructors before turning one of his five handguns on himself.

The same year saw Peter Odighizuwa, a graduate student at Virginia's Appalachian School of Law, kill the dean, a professor and a student before being tackled by students.

The campus attack with the highest death toll was the 2007 Virginia Tech massacre.

Gunman Seung-Hui Cho killed 32 people and wounded 25 others before killing himself.

In 2011 Radford University student Ross Truett Ashley, 22, killed a police officer on the campus of Virginia Tech, before killing himself.
