Baltimore remains tense after violence, looting

Washington, April 29, 2105: Some 2,000 National Guardsmen and more than 1,000 police officers stood guard as a tense Baltimore City, just 60 km from the US capital, slipped under night curfew after two days of riots over the death of a black man in police custody. Presidential candidate Hillary Clinton described his death as "a tragedy that demands answers". Hundreds of defiant protesters refused to leave the streets Tuesday night, and were facing off against gathered police officers after the riots that left more than a dozen buildings damaged, destroyed or looted and at least 20 officers injured. At least 235 people have been arrested, 34 of them juveniles. Protesters threw objects at the police when they first advanced on the crowd, and police responded with smoke grenades and flash-bangs about half an hour after the curfew went into effect at 10 p.m, according to various media reports. Monday's violence in Baltimore started hours after the funeral of Freddie Gray, a 25-year-old black man who suffered a serious spine injury while in police custody. His death on April 19 at a hospital led to several days of mostly peaceful protests.
