Baghdad (CNN) -- Thousands of mourners turned out in Falluja Saturday, hours after a powerful Sunni sheikh called on Iraq's Shiite prime minister to hand over soldiers responsible for killing anti-government protesters in Anbar province or face "losses among their ranks." The warning came as reports emerged that four soldiers were killed and four were abducted after security forces fired on a Sunni anti-government protest in Falluja, raising fears of retaliations that could ignite sectarian violence. Sheikh Ahmed Abu Risha, who is credited with rallying Sunni tribal leaders to turn on al Qaeda in Iraq, gave Prime Minister Nuri al-Maliki's government seven days to hand over to Anbar's criminal court those involved in the shootings.
