The Department of US Treasury imposed Tuesday sanctions on the senior commander in Haftar's forces, Mahmoud al-Werfalli, for committing human rights violations.

“On the International Human Rights Day, the US Treasury Department took action against 18 people for their role in gross human rights violations, including Libyan Mahmoud al-Werfalli who occupies the post of commander of a militia known as the "Saaiqa," the US embassy in Libya tweeted.

The sanctions included the prohibition of all of Werfalli's property and economic interests in the United States or any other territories under its control, as well as any entities owned by him, directly or indirectly, provided that his share exceeds 50%.

Al-Werfalli is responsible for, or complicit in, or participated directly or indirectly in serious human rights violations since 2016. He carried out or ordered the killing of 43 unarmed detainees in 8 separate incidents, according to the US embassy.

The US Department of State indicated that many of the killings linked to Werfalli were filmed and posted on social media.

On January 24, 2018, Al-Werfalli was filmed carrying out a mass execution of 10 unarmed detainees in Benghazi. The video shows Al-Werfalli shooting every detainee in his head, one by one.

Al-Werfalli also ordered the execution of 20 unarmed detainees, on July 17, 2017. In many incidents, He continued to shoot detainees even after their execution.

It is noteworthy that the International Criminal Court has issued several arrest warrants against Al-Werfalli.

However, Haftar's forces command recently announced that it will not extradite al-Werfalli, and he was released after interrogation.

Sources say Al-Werfalli is currently present in Haftar's forces waging the war on Tripoli.
