Indonesian authorities have blocked at least 11 websites and blogs after a terrorist attack in the capital killed two civilians, an official said Saturday.
The ministry also sought to block several social media accounts that expressed support for Thursday's attack, Information Ministry spokesman Ismail Cawidu said.
"We received complaints from the public about social media accounts and websites with radical content," Ismail said.
Most of the websites blocked were blogs hosted by blogspot.com.
Five men armed with explosives and handguns attacked a police post and a Starbucks cafe near the Sarinah shopping centre in the heart of Jakarta on Thursday, killing one Canadian and an Indonesian.
Two of the attackers blew themselves up while the other three died in a shootout with police, officials said.
Police arrested at least five suspects on Friday, but they were not directly related to the blasts, national police spokesman Anton Charliyan said.
Two of the attackers were former terrorism convicts, officials said.
Police said the attack was masterminded and funded by Bahrun Naim, an Indonesian militant who is now thought to be in Syria fighting alongside the Islamic State group.
Indonesia has faced problems in recent years with extremist violence, often linked to jihadi groups, and it is estimated that hundreds of its citizens have joined the Islamic State group in the Middle East.
