KABUL, Afghanistan — Four men were sentenced to death by an Afghan judge on Wednesday for the mob killing of a woman who had been falsely accused of burning a Quran. But the judge released many of the 49 defendants in the case and delayed verdicts for 19 police officers who were also charged.

The mixed ruling seemed unlikely to satisfy any observers of the trial, much of which was televised live. The killing of the woman, Farkhunda, 27, in broad daylight at a mosque in Kabul in March set off protests.

One of the four men sentenced to death is an amulet seller who falsely accused her of burning a copy of the Quran after she accused him of what she considered un-Islamic practices. Another of the men had claimed to be an intelligence official and had boasted of his involvement in the killing on Facebook. Witnesses said the third condemned man had kicked Farkhunda’s corpse and removed some of her clothing after she died, and the fourth threw particularly large stones at her while she was still alive.

Video of the killing showed a motorist deliberately driving over her head and then dragging her behind his car, but the driver is apparently one of several suspects not apprehended.
