A mudslide in Mocoa, near Colombia's southern border, has killed 112 people and injured at least 180 after intense flooding caused three rivers to burst their banks in the middle of the night.

Colombian President Juan Manuel Santos has confirmed that the current death toll has risen to 112 in an interview with local media.

Governor Sorrel Aroca told local media that 17 neighborhoods had been damaged by the flooding, with two bridges closed and electricity supply disruptions expected to continue, hampering emergency response efforts.

Dramatic footage showing the full force of the overnight flooding has emerged, showing heavy trucks been dragged down city streets.

"A big portion of the many houses were just taken by the avalanche, but above all the people were warned with enough time and they were able to get out, but houses in 17 neighborhoods have basically been erased," Mocoa Mayor Jose Antonio Castro told local radio station Caracol, as cited by Reuters.

Emergency workers are still searching for survivors and the death toll is expected to rise.

"The figures have been going up and in the crisis room they kept reporting more dead, we hope to God that (the death toll) will not go up too much because it is very sad," Castro added.

Carlos Ivan Marquez, director of Colombia's National Risk Management service, told local media that the Mocoa, Mulato and Sancoyaco rivers burst their banks at approximately midnight on Friday, March 31st, as cited by the AP.

Debris has been strewn across the city of 350,000 residents.

The Colombian military are on scene to assist with evacuations and relief efforts and a state of national emergency has been declared.

Colombian President Juan Manuel Santos expressed his condolences to the victims, his praise for the emergency services and is currently visiting the region reports the AP.
