FBI Suspects Boston Bombs Packed In Pressure Cookers

The FBI says the two bombs that exploded Monday at the Boston Marathon were carried in a dark-colored bag, and possibly consisted of pressure cookers packed with nails and ball bearings.

FBI examiners are looking at fragments recovered from the scene, as they try to piece together how the attack happened.
Authorities do not have any suspects, and are asking the public to send in any photos or videos taken along the marathon route to help find who was responsible
