Pakistani police say 13 members of a local tribal council who allegedly strangled a local girl and set her body on fire as punishment for helping one of her friends elope will face trial under anti-terrorism laws.

The body of 17-year-old Ambreen Riasat was found in a torched van near a tourist resort in northwestern Pakistan on April 29. Police say the tribal council ordered the killing.

Police officer Muhammad Tahir said Saturday the suspects are in the custody of counterterrorism police.

Nearly 1,000 women are killed every year in Pakistan in so-called honor killings in response to alleged romantic liaisons outside the bounds of arranged marriage. The killings are often carried out by close male relatives.
