PRETORIA, South Africa — Oscar Pistorius was indicted today on charges of murder and illegal possession of ammunition for the shooting death of the double-amputee Olympian’s girlfriend on Valentine’s Day.

A Pretoria court set March 3 as the trial date for Pistorius, who has said he shot Reeva Steenkamp by mistake, believing she was an intruder in his home. Prosecutors, who allege he killed her after an argument, submitted a list of more than 100 witnesses for a trial that will be followed around the world.

Pistorius, 26, appeared in court for the indictment.

The indictment papers served on Pistorius by the state mean the case will be sent to the High Court in Pretoria, where a judge will preside over the trial and ultimately pronounce the athlete innocent or guilty.
