An al-Qaida group has declared an election "curfew" in Iraq, warning Sunni Muslims they will face violence if they head to the polls on Sunday.
The Islamic State of Iraq posted a message on the Internet Friday, telling Sunnis that participation in the country's parliamentary election will only empower majority Shi'ite Muslims.
The Iraqi government has been increasing security in the days leading up to the election. Separate bombings near Baghdad polling stations killed at least 15 people Thursday, and U.S. officials say Iraqi security forces thwarted a number of potential attacks.
Despite the threat of violence, Iraqi religious leaders are urging their followers to vote in the elections, with some telling worshippers voting is their religious duty.
The nationwide poll is widely seen as a test of Iraq's ability to maintain security and conduct a smooth transition of power.
