Kenyan police have fired tear gas to disperse Muslim protesters who have looted shops and burned barricades for a second day in the coastal city of Mombasa.The protests follow the drive-by shooting of radical Muslim preacher Aboud Rogo Mohammed on Monday.The cleric had been accused by the UN and US of recruiting and funding Islamist fighters in Somalia.One person was killed and churches attacked in riots on Monday.Youths were fighting running battles with the police, who were using tear gas to try to disperse them, an eyewitness told the BBC.Shops have been looted and some are on fire, he said.Mr Rogo was on US and UN sanction lists for allegedly supporting Somalia's al-Qaeda linked al-Shabab militants.The UN Security Council imposed a travel ban and asset freeze on him in July, saying he had provided "financial, material, logistical or technical support to al-Shabab".It accused him of being the "main ideological leader" of Kenya's al-Hijra group, also known as the Muslim Youth Centre, which is viewed as a close ally of al-Shabab.He had "used the extremist group as a pathway for radicalisation and recruitment of principally Swahili-speaking Africans for carrying out violent militant activity in Somalia," the UN added.In 2005, Mr Rogo was cleared on murder charges over the 2002 attack on a hotel where Israeli tourists were staying, which killed 12 people.Some of the rioters accused the authorities of being behind Mr Rogo's shooting.
