A team of North Korean medical workers that arrived at a Libyan hospital earlier this year is now actively carrying out surgeries, treatments and consultations, according to the hospital, despite U.N. sanctions on DPRK laborers abroad.

Martyr Attia Al-Kaseh Teaching Hospital in Kufra city uploaded photos on social media last week that show the North Korean doctors receiving patients and even assisting with “orthopedic operations.” Many of the images show graphic surgeries as the DPRK medical workers stand next to the operating table.
