So we are learning more about what happened on Easter Sunday and what the authorities knew in advance of the bombings. The prime minister of this country, Ranil Wickremesinghe, speaking to CNN a short time ago, told CNN that intelligence here was tracking some of the suspected bombers but didn't move in to arrest them because they didn't have sufficient evidence. This as the investigation to stop any further bombings out there for making further attacks as that still unfolds. Israel's authorities have just issued a warning that there's a high concrete threat of further attacks. This is the latest number of warnings we've had over the week, warning people here that the threat of further terror attacks on this island is still very, very real. So we're learning more both about what happened on Easter Sunday and the threat that still exists over here -- Dave.</s>BRIGGS: We are still not out of the woods.
