Indonesian police expressed increasing confidence on Sunday that regional Islamist terrorist group Jemaah Islamiyah carried out last week’s double suicide bombing in two Jakarta luxury hotels as concerns mounted about President Susilo Bambang Yudhoyono’s crisis management in the wake of the attacks.

National police spokesman Inspector General Nanan Soekarna said investigators were now “almost certain” militants operating under Noordin Top, JI’s military commander, perpetrated Friday’s near-simultaneous bombings of the JW Marriott and Ritz-Carlton hotels that killed nine people.
