Authorities say suspect is 17-year-old male student and warn against terrorist attack speculation after Jakarta blasts

At least 54 people have been injured in explosions that shook a mosque at a high school during Friday prayers in the Indonesian capital, Jakarta. Authorities later said the suspect was a 17-year-old male student who had been injured and was undergoing surgery.

Witnesses told local television stations that they heard at least two loud blasts at about midday, just as the sermon had started, from inside and outside the mosque at SMA 72, a state high school within a navy compound in Jakarta’s northern Kelapa Gading neighbourhood.
