An explosion in a supermarket in northwest Colombia has left at least four people dead, and a further 10 injured.
The national police chief said a criminal gang - known as Los Urabenos - is being investigated over the blast on Tuesday evening.
However, he said the left wing guerrilla group Farc could also be responsible.
