More than 250 people have died in southwest Colombia following heavy rains, flooding and landslides over the weekend.

Photos from Mocoa, the capital of the Putumayo province ravaged by the disaster, show residents and emergency personnel walking debris-filled streets, digging through rubble in search of victims and waiting to identify bodies.

Downpours caused multiple rivers around Mocoa to overflow and push water, mud and rubble into homes as people slept, killing at least 254 people, Reuters reported. Another 400 people were injured, while 200 remain missing, the army said.

This was Colombia’s rainiest March since 2011, the BBC reported.

Colombian President Juan Manuel Santos traveled to the affected area on Saturday to oversee the emergency response.

“My heart and the hearts of all Colombians are with the victims of this tragedy,” he told reporters on the scene.
