Venezuela's Hugo Chavez announces new cancer operation

Venezuelan President Hugo Chavez has said he will return to Cuba on Sunday for more cancer surgery.

The Venezuelan leader only returned on Friday from his last course of treatment there.

"It is necessary for me to have a new intervention in the coming days," he said in a TV address, adding that more malignant cells had been found.
