Bomb attacks in the Indonesian capital Jakarta may have been the work of militants linked to Islamic State, deputy police chief Budi Gunawan says.
Budi says there were communication between an Islamic State operator in Syria and militants arrested in Solo, Central Java, in August for allegedly planning attacks.
"The Solo group has prepared cells to carry out what they called a 'bomb concert' that was supposed to be played on New Year's Eve," Budi is quoted by BBC Indonesia as saying. "But because we anticipated it, they only had the chance to do it now," he says.
Asked if the attack might have been carried out by Islamic State, like those in Paris, he says: "Yes, correct."
