Who's fueling the fighting in Libya?

The United Arab Emirates is accused of supplying fighters trying to seize Tripoli with anti-tank missiles made in the United States.

It’s a question being asked by Libya's internationally-recognised government in Tripoli.

And in Washington too.

How did US made anti-tank missiles sold to the United Arab Emirates end up on the battlefield in Libya?

The Libyan army, supporting the UN-recognised government, says boxes of the weapons, stamped with UAE logos, were found in Gharyan.

Troops recaptured the city on Wednesday, three months after warlord Khalifa Haftar took control there, using it as a springboard for his campaign to seize the capital.

Haftar has the support of regional powers, including Saudi Arabia and the Emiratis.

The weapons find raises questions about whether the UAE is violating internationally recognised US arms sales agreements as well as the UN arms embargo on Libya.
