Thousands of heavily armed police and soldiers barged past barricades into the capital's most violent slums on Tuesday, clashing with die-hard defenders of a gang leader sought by the United States. At least 30 people have died, officials said. Jamaica's security forces, reeling from bold attacks by masked gangsters loyal to underworld boss Christopher "Dudus" Coke, were in the midst of a nearly daylong assault in the heart of West Kingston's ramshackle slums, long afflicted by gang strife. But Coke was still at large despite the raid in his stronghold, National Security Minister Dwight Nelson told reporters at news conference. The suspect's lead attorney, Don Foote, has refused to say whether Coke was hunkered down in the barricaded Tivoli Gardens slum or was somewhere else in the country.
