mezzanine floor, instantly killing two and wounding 33. The bomb also partially damaged the building an estimated cost of
$250,000; windows up to 9 floors were shattered, multiple inner walls caved in, and hole was created in the ground floor. A taxi driver, who was struck by the blast, died two days later after being in a comma. The bomb was planted by two Indonesian marines as part of the
