Two teenage sisters have been shot dead in Pakistan for allegedly dancing in the rain.

Sisters Noor Basra, 15, Noor Sheza, 16, and their mother, Noshehra, were shot dead by five gunmen after a video of the two girls enjoying the rain shower in traditional dress spread throughout their conservative northern town.

The sisters' stepbrother is now being blamed for ordering their deaths on June 23 in an effort to restore the family's "honor" six months after the video surfaced.

That 22-year-old stepbrother, Khutore, has since been arrested for carrying out the attack according to police
