Jakarta – Prominent terrorist defendant and firebrand Muslim cleric Abu Bakar Ba'asyir may have orchestrated a series of terrorist attacks in several areas in Indonesia recently, National Antiterrorism Agency (BNPT) chief Ansyaad Mbai said Thursday at the Presidential Palace.

"There could be a possibility. We found similarities between the recent and previous attacks organized by the group of Abu Bakar Ba'asyir," he said as quoted by tribunnews.com.

A number of militant groups are suspected to have taken part in the most recent attacks, he said. Some of these groups, Ansyaad said, are the Islamic Indonesian State (NII), Jemaah Islamiyah and Jamaah Ansharut Tauhid.
