Philippine bomb probably terrorism

ABS CBN reports the bombs killing 4, including 2 congresspersons, was hidden on a motorcycle, surrounded by nails and set off by a carphone: All the marks of an Alqaeda bomb. They've been worried about this for awhile, since alqaeda trained JI terrorists from Indonesia have been instructing locals to make these bombs...and at least one such bomb making factory was destroyed by Philippine security last year.
