An explosion of a suspected smoke grenade on Tuesday at a park near Indonesia’s presidential palace injured at least two military personnel. The explosion took place at the National Monument park in the heart of the capital, Jakarta.
The presidential spokesman said that President Joko Widodo was not at the palace at the time.
It was not immediately clear if the blast was the result of a sectarian attack, but Indonesia has suffered a resurgence in homegrown militancy in recent years.
The explosion took off at 7:15 am (local time) on the north side of the park, was thought to have been caused by a smoke grenade, Jakarta police chief Gatot Eddy Pramono said at a news conference.
It injured two military personnel who were there for exercise, Jakarta military chief Eko Margiyono said, adding that they were taken to hospital and were conscious.
Authorities were yet investigating the attack.
Within three hours, authorities had reopened the park area where the blast took place, across the street from the headquarters of Indonesia’s home ministry.
Last month, six people were wounded after a 24-year-old university student blew himself up outside police headquarters in the Indonesian city of Medan.
The attack was linked to the Islamic State-inspired Jamaah Ansharut Daulah (JAD), responsible for a series of attacks across the country.
