The death toll climbed to 33 from a landslide that buried vehicles along a highway in Colombia over the weekend, Colombian Interior Minister Alfonso Prada said Monday. The landslide that happened on Sunday buried a bus carrying passengers from Cali, in the western Valle del Cauca department, to Condoto, in the western Choco department, along with a car and a motorcycle on the Pereira-Quibdo Highway in the western-central department of Risaralda. "We have identified 33 deceased people, including three minors. We have rescued nine people alive, four of them are currently in critical condition," Prada said.
