A suicide bomber on a motorcycle attacked a police station in the small Indonesian city of Solo on Tuesday, killing himself and wounding a police officer, a police spokesman said.

Following the attack, President Joko Widodo, who is from Solo and a former mayor of the town, urged calm and ordered police to quickly arrest others that may have been connected to the suicide bomber.

Police have increased security at churches, mosques, shopping malls and airports as Indonesia, home to the world's largest Muslim population, prepares to celebrate the end of the Islamic holy month of Ramadan.

"We are increasing the number of personnel, as well as intensifying patrols and security in places where there are a lot of people gathering," said police spokesman Agus Rianto.

Police said the attacker detonated the bomb he was wearing shortly after driving into the grounds of the police station in Solo, known as a hotbed for religious fundamentalism. A police officer who tried to stop him from entering sustained minor injuries.

The identity of the bomber was not immediately clear, but intelligence chief Sutiyoso told MetroTV he suspected the attacker was a supporter of ISIL terrorist group.
