The Muslim community in the Kenyan city of Mombasa has taken to the streets for the fourth day to protest the killing of cleric Aboud Rogo Mohammed. <br /><br />Rogo was murdered earlier this week and his followers claim he was executed by authorities over unproven allegations of "terrorism".<br /><br />He had been blacklisted by US and UN for his alleged support for Somalia's al-Qaeda-linked al-Shabab.<br /><br />Kenyan Muslims believe they are the victims of religious persecution and are convinced there is a systematic campaign of extrajudicial killings and disappearances of conservative thinkers in their community.<br /><br />Al Jazeera's Peter Greste reports from Mombasa.
