At least 10 people were killed and dozens injured after the earthen wall of a reservoir collapsed in eastern China, flooding a rural area, state media said Sunday.

The 29-metre (96-foot) wall, part of a reservoir in Zhejiang province, collapsed early Friday, following heavy rainfall after Typhoon Haikui passed through the area, the China Daily newspaper said.

The paper put the death toll at 10 while the official Xinhua news agency said Saturday that 11 people died and 27 were injured.

Local officials in Shenjiakeng village, where the accident took place, could not be immediately reached for comment.

The collapse flooded a "large area" of the village with water and silt, affecting 80 families and damaging at least a third of homes, China Daily said.

Haikui, now a tropical storm, had previously killed at least six people and continues to bring heavy rain to parts of eastern China, Xinhua has reported, quoting government statistics.
