The government has blocked access to about 300 Web sites that could inspire acts of terrorism, the minister of communication and information technology said on Monday.

"As of the end of August 2011, we had complaints about around 900 sites, but so far we have only managed to block 300 of the sites," Tifatul Sembiring said on the sidelines of the first Information and Communication Technology Expo and Conference, in Yogyakarta.

He said provocative Web sites could inspire acts of terrorism like the suicide bombing at a church in Solo on Sunday. The blast instantly killed the bomber and left dozens more injured.

The minister added that his office would scrutinize each reported Web site before taking any action to block access.

"If there is a complaint, of course we will take action, but it doesn't mean that as soon as we receive a report that we will automatically block it," he said. "We have to look at the site first."

"There have also been calls to block or shut down sites that attack certain religions and which could agitate the public," Tifatul said. "We will block them in stages."

Still, the minister said blocking access was not enough. "People must also digest any information available [online] more rationally so they aren't easily provoked," he said. Internet operators, Tifatul added, should still censor Web sites to eliminate provocative content.
