At least 20 people are missing after torrential rains lashed the city of Manizales, officials said, raising fears the death toll could soar as it did earlier this month in the southern city of Mocoa.
There, at least 323 people including more than 100 children were killed when heavy rain caused three mountain rivers to flood on March 31, hurling a tidal wave of mud and boulders into the city.
Manizales 'is literally cut off by rock slides, mudslides, floods', Mayor Jose Octavio Cardona told local radio stations.
He said on Twitter he had ordered officials from the emergency agency and transport ministries to the city to assess the 'grave situation'.
