At least 20 killed in Colombia mine explosion

An explosion at a coal mine in Colombia has killed at least 20 workers. The blast was at Sardinata in the north of the country.

Another blast at the same mine four years ago killed 32 people. The local mayor has said rockfalls have been preventing rescue workers getting into the mine.
