Oscar Pistorius sobs on stand in murder trial, forcing another delay in cross examination

PRETORIA, South Africa -- A judge temporarily adjourned the murder trial of Oscar Pistorius Monday after the athlete started to sob while testifying about the moments before he killed girlfriend Reeva Steenkamp in his home last year.

Pistorius said he thought there was an intruder in the house and that he screamed, using an expletive, for the purported intruder to get out of his house. As he testified, he began to wail.

The proceedings resumed after a brief delay. Nel continued to ask Pistorius about his remarks before he shot Steenkamp, and the manner in which he held his gun as he approached the closed toilet cubicle door.

The prosecution says Pistorius' account of a mistaken shooting is a lie.
