Judge says Oscar Pistorius must undergo psychiatric tests

The judge in the trial of Oscar Pistorius says he must undergo a month of daily tests to establish his mental state when he killed girlfriend.

Judge Thokozile Masipa ordered the South African athlete to attend Weskoppies psychiatric hospital in Pretoria as an outpatient.

Mr Pistorius denies intentionally killing his girlfriend Reeva Steenkamp.

He says he accidentally shot her through the toilet door in a state of panic, mistaking the 29-year-old model and law graduate for an intruder.
