"Wherever we find Americans we will kill them, but we don't have any connection with the Boston explosion," said a spokesman for the group, which claimed responsibility for the attempted Times Square bombing in 2010. Police say nobody is in custody in connection with the bombing, but they are speaking to a Saudi citizen who was injured in the blast, the New York Times reports. The Saudi, who is in the US on a student visa, was seen running from the scene of the first blast but it's not clear whether he was involved, law enforcement officials say. Police and a large number of federal agents descended on an apartment complex in the Boston suburb of Revere last night, the Boston Herald reports. Police have confirmed that the search was related to the blasts, the AP reports. Three people were killed and around 140 people were injured, some critically, by the twin explosions, which law enforcement sources tell Reuters involved devices that used gunpowder as the explosive and were packed with ball bearings and other shrapnel to maximize injuries. A senior intelligence official speaking under condition of anonymity says up to two unexploded devices were found near the marathon finish line but were safely disarmed.
