Jurors have decided whether to sentence Colorado cinema gunman James Holmes to death or send him to prison for the rest of his life.

Holmes, a former neuroscience graduate student, killed 12 people and wounded 70 others during a late night screening of a Batman film in 2012.

The decision will be announced at 5pm local time (23:00 GMT) in a courtroom in Centennial, Colorado.

His defence team had argued that he was insane at the time of the shootings.

But prosecutors said that Holmes, though mentally ill, was responsible for his actions, and the jury agreed.

He will only receive the death sentence if the jury is unanimous.

In July, Holmes was convicted on 165 counts of murder, attempted murder and an explosives charge.
