JOS, Nigeria, January 19, 2010 SPA -- Sectarian violence erupted again Tuesday in Nigeria, as security forces issued a 24-hour curfew for the city of Jos where rioters have burned homes and killed at least 27 people, The Associated Press reported. Security forces ordered everyone to remain indoors after police and soldiers' efforts to contain the violence with roadblocks and searches apparently failed. Calm returned to the city Monday, but police refused to offer any casualty count. Sani Mudi, a spokesman for the local imam, has said 22 people died Sunday and more than 300 people were wounded in the fighting. Five others died Monday from their wounds, Mudi said. --SPA 14:59 LOCAL TIME 11:59 GMT www.spa.gov.sa/739517
