BRIGGS: Police in Sri Lanka now warning that more suspects in the Easter Sunday bombings could still be on the run as the investigation into the terror attack widens. The Defense minister resigning after taking responsibility for a significant intelligence failure. CNN's Ivan Watson live in Colombo for us. Ivan, good morning.</s>IVAN WATSON, CNN SENIOR INTERNATIONAL CORRESPONDENT: Good morning, Dave. That's right. The concerns are very real here in the Sri Lankan capital. You have police and soldiers deployed all over the place as there are fears that there could still be, as the prime minister put it to me yesterday, sleepers out there who want to do more harm. Israel has issued a threat level one warning and the U.S. says that terrorists can attack with no warning hitting everything from places of worship to hospitals to shopping malls to restaurants, any place where people gather And just driving around the city, I argue that probably half of the shops and businesses seen closed right now, the shopping mall we went to was almost deserted. There is real fear out there right now, and it extends of course to the religious communities, certainly the Catholic community, the leader of the Catholic Church here, has suspended all church services until April 29th. The minister of Muslim Religious Affairs has urged the country's Muslim minority not to go to mosque for Friday prayers in solidarity with the Christians who were so viciously targeted on Sunday. And there is up the road here a Sufi Muslim mosque in the distance with probably 20 police and soldiers in front of it. The Sufi Muslims are also a potential target. There have been threat warnings to them because in ISIS's hateful ideology, Sufi Muslims are considered heretics and thus have been targeted in this country in the past. It gives you a sense of how frightening the situation is right now -- Dave.</s>BRIGGS: I can't imagine, Ivan, for everyone there including you guys and our team, just a terrifying situation. Just about 2:00 p.m. in Sri Lanka. Ivan, thanks.</s>KOSINSKI: Well, Joe Biden could be kryptonite for the president if Biden's own history doesn't slow him down.
