NATO accused Libyan leader Moammar Gadhafi on Saturday of using mosques and children's parks as shields for his military operations, saying the longtime ruler who lashed out against alliance airstrikes is the one "brutally attacking the Libyan people." Hours later, at least two explosions shook Tripoli as NATO jets soared above the capital. It was not immediately clear what had been hit or if there were casualties in the late afternoon raid. In a telephone call piped through loudspeakers to a few thousand people demonstrating in Tripoli's Green Square on Friday, Gadhafi railed against NATO following a day of intensified bombing runs in the capital. NATO's mandate is to protect civilians amid a four-month uprising that has devolved into a civil war. "NATO will be defeated," Gadhafi yelled in a hoarse, agitated voice to the crowd. "They will pull out in defeat." In Brussels on Saturday, NATO spokeswoman Oana Lungescu dismissed Gadhafi's speech as "outrageous."
