Jakarta, Indonesia (AP) - Explosive material recovered from the scene of two suicide bombings at hotels in the Indonesian capital is "identical" to that used by the Southeast Asian terrorist network Jemaah Islamiyah in earlier attacks, police said. An unexploded bomb left in a room of the J.W. Marriott in Jakarta resembled devices used in attacks on Bali and one found in a recent raid against the network on an Islamic boarding school in Central Java, national police spokesman told a news conference Sunday.
