"We have seized a backpack from the perpetrator. The perpetrator is alive and injured and there are no casualties in this incident," Insp. Gen. Boy Rafli Amar said, as quoted by the Jakarta Globe.
He added that following the incident, police found a drawing that looked like a Daesh flag.
Indonesia, the largest Muslim country in the world, is home to a large number of Daesh fighters; the terrorist group has been condemned by Russia and other countries around the globe.
