Supporters of an unsuccessful presidential candidate clashed with security forces in the Indonesian capital today, burning vehicles and throwing rocks at police, which responded with tear gas and rubber bullets.
The protesters tried to force their way into the downtown offices of the election supervisory agency yesterday and clashes have continued since then.
National Police spokesman Muhammad Iqbal said the majority of protesters had come from outside Jakarta and nearly 60 suspected provocateurs had been arrested.
Local media reported several deaths and dozens of injured among protesters. The governor of Jakarta, Anies Baswedan, who is aligned with losing presidential candidate Prabowo Subianto, said there were six deaths though there has been no official confirmation.
White-robed men blocked streets in one central Jakarta neighborhood and in another, rioters fought running battles with police, throwing rocks and setting fires.
During the night, vehicles and a paramilitary police dormitory were set ablaze as police using tear gas, rubber bullets and water cannon battled protesters who threw Molotov cocktails and burning projectiles.
