Ten days before the Easter bombings, India had sent Sri Lanka a detailed advisory that warned not only of the suicide attacks, but the group involved, the names of its leader and other members. 359 people had died and around 500 wounded in the string of bomb blasts on Sunday that targetted hotels and churches. So far, 60 people have been arrested. The three-page advisory, which has been accessed by NDTV, mentioned the group involved as the National Thowheeth Jama'ath. It had the whereabouts of those involved -- the addresses of their hideouts, phone numbers and background.
