Friday prayers have resulted in the injury of over 50 people in explosions in an Indonesian mosque, and the police have identified the 17-year-old student as the possible attacker.

It occurred at approximately 12:15 local time (05:15 GMT) on 7th November within a school block, which contained the mosque in Kelapa Gading, a district of the capital, Jakarta.

The victims who were predominantly pupils were injured in diverse ways, including severe burns. Indonesian police chief, Listyo Sigit Prabowo, also claimed that the suspect was injured.

He also mentioned that the investigation of the incident is in progress, not excluding how the suspect was assembled and conducted the attack.

The explosions prompted a bomb disposal team to go to the state-run high school complex to collect the evidence and to make sure that there were no other explosive devices.

One of the pupils at the state-owned news agency in Indonesia, Antara, reported to the government that a self-made bomb had been smuggled into the school by a student who was frequently bullied by his peers.

The other students informed Indonesian news agencies that the suspect was a loner who tended to draw pictures of violence, and that he was found lying on the floor after the blast had happened.

A school cook recounted that the mosque had white smoke preceding the windows after the massive explosion.

“Our hearts were racing, we were unable to breathe,” the survivor told the Reuters news agency.

The Jakarta Metropolitan Police confirmed that there were two objects that looked like guns at the scene, by confirming this information through a high-ranking police officer.

According to the pictures taken in Antara, one of the items seemed to be a submachine gun, and another one was a pistol.

The object, which is the submachine gun, seems to be engraved on its barrel with “14 words for Agartha.”

It is marked on its body with the following: “Brenton Tarrant. Welcome to Hell.”

The offender of a 2019 mosque and Islamic centre mass shooting that claimed 51 lives and injured dozens more in Christchurch, New Zealand, is Brenton Tarrant.

A minister who paid a visit to the scene later on Friday attempted to deny allegations that there would be any weaponry in the scene, and, talking to CNN Indonesia, said the depiction had been imaginative, much like a toy gun, not a real one.

Lodewijk Freidrich Paulus also addressed the people not to assume that it was a terrorist act, given the fact that law enforcers were still picking up the area.

The other item discovered at the location was a dark green belt that was used to store gun cartridges.

The largest population of Muslims is found in Indonesia.
