Pakistan's paramilitary officers take away unidentified radical religious students in a police vehicle near the Red Mosque, or Lal Mosque, in Islamabad July 6, 2007. A Pakistani cleric holed up in an Islamabad mosque said on Thursday he and his student followers were willing to surrender, after three days of violence in which 19 people have died. But authorities rejected his offer, saying his attempt to attach conditions was unacceptable and insisting he release women and children human shields.
