BABAKOT, Pakistan – In a tangle of bushes and trees outside a remote village in southwest Pakistan, six close male relatives of three teenage girls dug a 4-foot wide by 6-foot deep ditch, on a sweltering night in mid-July, and allegedly buried the girls alive.

The girls' crime: they dared to defy the will of their fathers and the customs of their tribe and choose their own husbands. The mother of one of the girls and the aunt of another were shot and killed while begging for the girls’ lives, according to local media reports.

The incident has touched off widespread condemnation from human rights groups, but also a sturdy defense from local officials. "This action was carried out according to tribal traditions," said Israrullah Zehri, a senator representing Balochistan in the upper house of Pakistan’s parliament in the capital Islamabad. "These are centuries-old traditions and I will continue to defend them," he said.
