The National Bureau of Investigation (NBI) will also investigate the two explosions at the Our Lady of Mt. Carmel Cathedral in Jolo, Sulu on Sunday, Jan. 27.
Thru a department order dated Monday, Jan. 28, Justice Sec. Menardo Guevarra authorized NBI Dir. Dante Gierran to conduct an investigation and case build-up on the two bombing incidents that killed at least 20 people and injured more than 100 others.
Currently, the Philippine military suspects the Ajang-Ajang group, a faction of the Abu Sayyaf Group, to be behind the twin blasts.
The Philippine National Police also suspects that Kamah, the brother of a slain ASG leader, was involved in the explosion since
closed circuit television footage showed he was around the chapel before the explosion.
