A suicide bomber detonated an explosive devise in front of the Surakarta Police headquarters in Central Java on Tuesday, injuring a police officer, said a police representative. The unidentified suicide bomber is reported to have died from injuries sustained during the attack.

A motorcyclist attempted to break through a security barricade and, when an officer attempted to stop the approach, detonated a bomb, explained the Surakarta Police spokesperson.

The alleged attack occurred a few hours after a series of bombings were set off in three cities in Saudi Arabia, including Madinah, considered a sacred Islamic site. The attacks in Saudi Arabia, which left four people dead, followed a bloody week of bomb attacks in Turkey, Bangladesh and Iraq.

The authorities are still investigating the motive behind the attacks. It is believed that the Islamic State (IS) militant group, which has vowed to step up attacks outside of Iraq and Syria, may have been responsible.

On Jan. 14, IS claimed responsibility for an attack in Central Jakarta, that left four civilians and four assailants dead. (ary)
