Colombian anti-drug authorities have dealt a heavy blow to smugglers in the past two days, seizing more than 11 tons of cocaine, police said Saturday.

At least seven tons of cocaine, heading for the United States and hidden in several containers, were seized in the Caribbean coastal city of Cartagena in northwest of the country Saturday.

On Friday, the police found around 4.3 tons of cocaine at the port of Barranquilla, another Caribbean coastal city in Colombia. The drugs were also hidden in containers, with Mexico as the planned destination.

According to police statistics, the Colombian authorities have seized 24 tons of cocaine this year, half of last year's total.
