Colombia landslide death toll rises to 234: Red Cross

Bogota: The toll has risen to 234 dead in a violent landslide in Colombia caused by the overflowing of three rivers swollen by torrential rain, the local Red Cross said on Sunday.

Hardest-hit was the southwestern town of Mocoa, in the Amazon rainforest basin, with the previously reported number of fatalities hitting 206.

At least 202 people were wounded, more than 100 people missing, 300 families affected and 25 homes destroyed, the Colombian Red Cross said, citing information complied from rescue workers.

In the southwestern Colombian town of Mocoa, the surge swept away houses, bridges, vehicles and trees, leaving piles of wrecked timber and brown mud, army images from the area showed.

The mudslides struck late on Friday after days of torrential rain in the Amazon basin area town of 40,000.

"The latest information we have is that there are 206 people confirmed dead, 202 injured, 220 missing, 17 neighbourhoods hit hard," Colombian Red Cross chief Cesar Uruena told AFP on Saturday.

President Juan Manuel Santos visited Mocoa, the capital of Putumayo department, yesterday to supervise rescue efforts in the heavily forested region.

He declared a public health and safety emergency to speed up rescue and aid operations. He also expressed his condolences to victims' families.

Putumayo Governor Sorrel Aroca called the development "an unprecedented tragedy" for the area.

There are "hundreds of families we have not yet found and whole neighbourhoods have disappeared," he told W Radio.

Carlos Ivan Marquez, director of the National Disaster Risk Management Unit, told AFP the mudslides were caused by the rise of the Mocoa River and tributaries.

The rivers flooded causing a "big avalanche," the army said in a statement.

Some 130 millimeters of rain fell Friday night, Santos said. "That means 30 per cent of monthly rainfall fell on last night, which precipitated a sudden rise of several rivers," he said.

He promised earlier on Twitter to "guarantee assistance to the victims of this tragedy, which has Colombians in mourning."

"Our prayers are with the victims and those affected," he added.

The authorities activated a crisis group including local officials, military personnel, police and rescuers to search for missing people and begin removing mountains of debris, Marquez said.

A thousand emergency personnel were helping the rescue effort. Mocoa was left without power or running water; there were reports of some looting in efforts to get water.
