ND says police have been questioning the only attacker who was captured alive: this attacker said he has support from a militant group which is based in Karachi, Pakistan. He told investigators that he joined the group 3 years ago when he was 19 and he received all kinds of training from them. (Does this synch with any other information that police have of this group in Pakistan? How credible is what he's saying?) This is just initial information coming in from this person. It all needs to be cross checked and verified. (Has this attacker given any motive?) The motive is not very clear as of now. These people just wanted to kill as many people as they could, it appears. They're still looking for other leads though. (Are folks still worried that more attackers are still out there?) Yes absolutely, that is a big fear. Some sources have said that could be a possibility too.
