earlier today, i spoke to jane arraf of al jazeera english in baghdad. jane arraf, welcome. tell us more about the targets here. they were clearly aiming at shiite neighborhoods and institutions? >> they were for the most part, jeff. mostly shi'a neighborhoods. in fact, even some in... near a shi'a shrine. but they were also aimed at security forces. some of them were gunmen opening fire on police here in baghdad and mystifyingly one of the targets appeared to be an elementary school. this was in the town of hillah... near the town of hillah south of baghdad where a car bomb exploded just outside the gates of a primary school injuring dozens of children. so a wide range of targets but all of them with a common denominator of seemingly seeking to destabilize security services here and instill fear-- which they did. >> brown: well, what is known about the insurgents who might have carried this out? who are they and tell us more about their possible aims? >> everyone's blaming it on al qaeda. "everyone" meaning from the interior ministry which said al qaeda was clearly to blame
