This is the bizarre moment two coconut-picking monkeys started fighting while they were waiting at a set of traffic lights.

The primates - used to collect the fruits - were chained to the side of the vehicles in Chumphon province, southern Thailand, on Friday (September 11).

There was a full harvest of fresh coconuts in the back of the pick-trucks that the monkeys had helped to collect after long hours of work. 

The pair were returning home when they began squabbling. One of the animals then launch a flying-kick out at the other as they faced off at the junction.

A passenger who was sitting in the traffic behind the two monkeys recorded the unusual incident. 

It gives an insight into the condition that monkeys face while they are working in the controversial coconut harvesting industry, which was exposed by animal rights group PETA earlier this year.

The group found farms in Thailand training monkeys to pick coconuts from trees, sometimes being forced to carry items larger than their own bodyweight.

It lead to several supermarket taking banning the products. 
Waitrose also vowed not to sell products made with animal labour after after the investigation showed that popular brands were exploiting primates.

Other companies including Boots, the Co-op and Ocado have also pledged not to sell products that use monkey labour, while Morrisons has removed the Thai products from its shelves.
