It seems suicide bombers are on rampage across the globe.

Few days after two teenage bombers blew themselves up in Nigeria, another set of militants on a motorcycle blew themselves up at a police headquarters in Indonesia’s second city Surabaya on Monday. 

The explosion wounded at least 10 people including officers, authorities said, a day after a deadly wave of suicide bombings hit churches.

Citing CCTV footage from the scene, East Java Police spokesman Frans Barung Mangera said a man and a woman on the bike stopped at the security checkpoint.

“That’s where the explosion happened,” he added.

“Two people were riding (on the motorcycle) and a woman was sitting at the back.”

The authorities said the wounded included six civilians and four police.

Ambulances and the bomb squad descended on the chaotic scene with the CCTV images showed the mangled wreckage of a motorbike at the security gate at the headquarters in the heart of the city.

There was no immediate claim of responsibility after the latest suicide bombing.

“This is a cowardly act, undignified and inhumane,” Indonesian President Joko Widodo told reporters in Jakarta.
