DERA ISMAIL KHAN (Pakistan): The most hated man in Pakistan is a 36-year-old father of three and volleyball enthusiast nicknamed "Slim".
His real name is Umar Mansoor and the Pakistani Taliban say he masterminded this week's massacre of 132 children and nine staff at a school in Peshawar - the deadliest militant attack in Pakistan's history.
A video posted on Thursday on a website used by the Taliban shows a man with a luxuriant chest-length beard, holding an admonishing finger aloft as he seeks to justify the December 16 attack. The caption identified him as Umar Mansoor.
"If our women and children die as martyrs, your children will not escape," he said. "We will fight against you in such a style that you attack us and we will take revenge on innocents."
