JAKARTA (Reuters) -An explosion at a mosque in Indonesia's capital Jakarta during Friday prayers that injured dozens of people could have been an attack, officials indicated, with a 17-year-old identified as the "suspected perpetrator".

The country's deputy house speaker Sufmi Dasco Ahmad, speaking to media after visiting a hospital, said the suspect was currently undergoing surgery.

Jakarta city police chief Asep Edi Suheri told reporters 55 people had been admitted to hospitals with a range of minor to serious injuries, including burns from the blast at the mosque inside a school complex in the Kelapa Gading area.

An investigation was underway, police said.
