Bahrain is stepping up pressure on anti-government activists ahead of elections this week, warning they could face jail for posting Web messages urging protests or other acts of dissent.
The Interior Ministry statement is part of wider security measures taking shape Thursday before the highly charged parliamentary elections. It says that charges could be filed against anyone using social media and websites to urge for demonstrations or anti-state actions.
Some Shiite-led groups are calling for escalated protests to press demands for greater rights from the Sunni monarchy.
The voting on Saturday is for 18 parliament seats abandoned by Shiite lawmakers six months ago to protest the crackdowns. Main Shiite blocs have urged a boycott.
