Two teenage girls have been shot dead in an apparent honour killing in Pakistan after a video was circulated showing them dancing in the rain.

The girls, aged 15 and 16, are seen running around wearing traditional dress, covered in green and purple headscarves, outside their stone bungalow in the town of Chilas, in the far north of the country.

The sisters were filmed dancing in the rain before being shot dead in an apparent 'honour' killing.

Local media named them as Noor Basra and Noor Sheza, the daughters of a retired police officer. According to Dawn newspaper, five masked men barged into their house and opened fire last Sunday. Their mother was also killed.

The report said police believed that the crime was motivated by a video clip circulated on mobile telephones. The short film, shot six months ago, shows the girls smiling and laughing as they run around their home, breaking into a dance.
