US accused of assassinating Abbas
Mr Abbas, also known as Abu Abbas, was captured by American forces in Iraq nearly a year ago and Washington vowed to bring him to justice. The US military in Baghdad confirmed his death in detention, one official attributing it to a heart attack.
"We hold the Americans responsible for his death, for his assassination," said Omar Sheble, number two to 56-year-old Abbas in the Palestinian Liberation Front (PLF). "They put him to die slowly in a prison cell, deprived of his freedom. His detention was illegal and his conditions in jail were bad," he said.
