Colombia ? An intense rainstorm triggered a landslide that buried part of a shantytown on the outskirts of the northwestern city of Medellin, killing at least 26 people, many of them children, officials said Friday.

Rescuers on Friday recovered the bodies and continued digging through the mud as nearly 30 people remained missing, said Claudia Helena Velez, a municipal official in Bello, 160 miles northwest of Bogota.

The landslide, which brought mud, trees, garbage and rocks sweeping through the town of Bello, occurred late Thursday after five hours of heavy rains that loosened the earth in the boulder-covered mountain above the town.

At least 11 of those killed were children, said Gen. Ruben Carrillo, police chief of Antioquia state.

About a dozen homes, many made of plywood with tin roofs, were destroyed, and entire families were killed by the mudslide.
