Quake death toll rises as key rescue period passes

The death toll from Sunday's earthquake in Yunnan province rose to nearly 600 on Wednesday as a key 72-hour period for rescue work passed.

The magnitude-6.5 quake has killed 589 people and injured more than 2,000 others.

Although the 72-hour "golden period" had passed, rescuers were still trying to find residents buried in rubble.
