Blood stains are seen on a riot-police car after a fight between nationalised Sunnis and Shi'ites in Hamad Town, south of Manama March 3, 2011. Sunni and Shi'ite Muslims clashed on Thursday, the first direct confrontation between the two sides since large scale protests erupted in the kingdom's main city two weeks ago. Residents said a group of Shi'ites fought with a group of Sunnis and what they said were Bahrainis of Syrian extraction. REUTERS/Hamad I Mohammed (BAHRAIN - Tags: POLITICS CIVIL UNREST)
