Balochistan Senator Sardar Israrullah Zehri stunned the upper house on Friday when he defended the recent incident of burying alive three teenage girls and two women in his province, saying it was part of "our tribal custom." Senator Bibi Yasmin Shah of the PML-Q raised the issue citing a newspaper report that the girls, three of them aged between 16 and 18 years, had been buried alive a month ago for wishing to marry of their own will. The barbaric incident took place in a remote village of Jafarabad district and a PPP minister and some other influential people were reported to have been involved. The report accused the provincial government of trying to hush up the issue. Ms Shah said that the hapless girls and the women were first shot in the name of honour and then buried while they were alive. She also said that no criminal had been arrested so far.
