Six boats and 23 people were detained in the record drugs bust, as Mexico faces pressure from the US to do more to stop trafficking.

A drugs haul weighing more than an elephant has been seized in the Mexican navy’s biggest ever drugs bust.

The operation saw 23 people arrested off the country’s southwest coast.

The haul weighed some 8,400kg - an elephant can weigh up to 6,000kg on average, according to the WWF.

“This represents the largest quantity of drugs seized in a maritime operation, without precedent in the history of the institution,” the navy said in a statement.
