The government is weighing the option of restricting use of social-networking sites, such as Twitter and Facebook, in an effort to quell the protests that have rocked Turkey for several weeks, press reports said Tuesday.

The Justice Ministry is working on a bill covering Internet crimes, the Hurriyet newspaper reported on its Web site.

"We are reviewing international regulations on this matter," the newspaper reported, citing government sources.

A special government agency is examining about 5 million Twitter postings made during the protests, Hurriyet said.

Police are taking action against individuals suspected of inciting protests on Twitter, Interior Minister Muammer Güler told reporters on Monday.

"We have a study on those who provoked (protests) by the citizenry via manipulations and false news on Twitter and Facebook, leading to actions that could endanger public safety and property," the minister said.

Prime Minister Recep Tayyip Erdogan, meanwhile, once again defended the actions of riot police and accused demonstrators of firing shots at officers. EFE
