Thousands of Sunni Bahrainis gather near the home of a Sunni family to protect the household from Shi'ites they believe are intending to attack them, in the town of Busiteen, north of Manama, early 8 March 2011. A member of the Sunni family was involved in a car accident that injured a Shi'ite who was protesting at Bahrain's Financial Harbour on Monday night, and people from the Sunni community turned up to defend the family against possible reprisals from the Shi'ites.
