A Libyan court sentenced five Bulgarian nurses and a Palestinian doctor to death on Tuesday for deliberately infecting hundreds of children with the virus that causes Aids, provoking a chorus of Western condemnation.The ruling in a deeply politicised case could set back oil producer Libya's hopes of better ties with the West, which meant a deal to save the six from execution was still likely, analysts said. The children's relatives broke down in tears and hailed the ruling, which ended a seven-month retrial, as a welcome act of defiance of the West. "Justice has been done. We are happy," said Subhy Abdullah, whose daughter Mona, 7, died from Aids contracted at the hospital in the town of Benghazi where the medics worked.
