Authorities said on Sunday that flooding and rain-triggered landslides left more than 100 people dead or missing in a northeastern China province in recent days.

Civil affairs officials in Jilin province also told the state-run news agency Xinhua about 37,000 houses had collapsed and 125,000 others were damaged. Days of torrential rains also had forced the evacuation of 592,000 people.

It has been reported that provincial officials told Xinhua flash floods had cut roads and disrupted communications, leaving villages isolated, and filled seven of 18 reservoirs behind large dams to dangerous levels. The flood waters also sent thousands of chemical-filled barrels floating down the Songhua River.

Sun Jingyuan, a senior official in Antu County where 70 houses in one village were swept away, said, "The flood is unprecedented. It's devastation is appalling."

The forecast calls for more heavy rains until Wednesday.

It has further been reported that large regions of the country have been inundated by deadly floods in the past month.

The government's year-to-date figures showed 991 deaths and 558 missing in natural disasters as of Friday, Xinhua has said. (With Inputs from Agencies)
