BOLDUAN: ISIS is now claiming responsibility for another deadly attack in another major city, Jakarta, Indonesia, the capital of the fourth most-populated nation in the world. Terrorists launched a series of assaults much like the horrific ones just weeks ago in Paris.</s>BERMAN: At least five attackers with guns and bombs targeted a busy commercial hub at the heart of the city. It left at least two people dead, nearly 20 hurt. Authorities say the attackers were killed. But now they're looking for anyone who might have helped them. CNN's Kathy Quiano joins us live from Jakarta. Kathy, what are you learning?</s>KATHY QUIANO, CNN PRODUCER, INDONESIA: We know police officials here are undergoing an investigation, they are investigating who might be behind these attacks. They're looking at who may have planned this, who may have funded this, because from information we're getting from them today, it's very clear this was very well executed, it was well funded, there were resources here that authorities here for a long time thought was not available to existing terror networks here. They did say many times in the past that the terror threat was low, but now that has changed. There were guns, explosives. At least 10 bombs. Five of them exploded. Five unexploded devices were later found on the site as well. There were pistols. And the nature of the attack as well and the targets. It has been a fact here for a long time that attacks, which were quite minor over the past -- over the recent years, targeted police authorities and government authorities. And this time, they were targeting foreigners, according to police officials. And certainly that's part of the investigation here.</s>BERMAN: Still a lot of questions. They are on the hunt for possible accomplices. Kathy Quiano. Again, ISIS now claiming responsibility for this attack that hit Jakarta overnight. Thanks, Kathy. Coming up for us, leaping off very tall buildings, bridges, with just a parachute and perhaps, you know, maybe a drink beforehand. This crazy sport is known as base jumping and there's a fantastic new CNN Film about it. We're going to talk to a former base jumper about why on earth he did it and why on earth he quit.
