Bahrain says it has deported a U.S. citizen teaching there over her "radical" writings on Twitter and websites as the Gulf kingdom cracks down on dissent.

A statement Saturday from the Ministry of State for Communications said the teacher published articles about Bahrain that "were deemed to incite hatred against the government and members of the royal family."

The ministry said the woman, whom it did not identify, also violated the terms of her work permit by working illegally as an unaccredited journalist. The ministry said she also wrote for the Bahrain Center for Human Rights.

Bahrain, home to the U.S. Navy's 5th fleet, has faced 18 months of unrest between the Sunni-led monarchy and its majority Shiite population. The government has started a crackdown on dissent.
