A landslide in north-west Colombia has killed at least 23 people and injured around 30 more, local authorities say.

The road connecting the cities of Medellín and Quibdo had been closed by several landslides, so many people stopped their cars to take shelter in a house near the community of Carmen de Atrato, a local official said.

Another landslide then struck the road, burying them and some of the vehicles.
