A Malaysian fishing boat rescued an Acehnese woman who had been drifting in the Indian Ocean for five days after last week's devastating tsunamis, officials said today.

The woman in her 20s was found floating alive Friday not far from the shores of Indonesia's Aceh province, the area hardest hit by the Dec 26 disaster, a Malaysian International Tuna Port official told Bernama news agency.

"From initial information received from the crew, the woman, with leg injuries, is safe," he said.

He added the woman would be hospitalised for treatment once the ship arrived back at the port on the north Malaysian island of Penang later today.

The ship did not report any major damage from the killer giant waves triggered by an undersea earthquake measuring 9.0 on the Richter scale.
