Pakistan's Supreme Court has sent a fact-finding mission to a remote northern area to establish if four women have been killed, following reports that they had been sentenced to death by a local tribal council or Jirga.

It has been reported that the women, along with two men, were condemned when video footage showed them singing and dancing at a wedding.

Local officials told the court they had been unable to contact the women, despite several attempts, as the BBC's Orla Guerin reports.
