The United States blacklisted on Monday a militia leader in Libya’s Misrata city. The US State Department said Salah Badi was being sanctioned because he had worked to undermine Libyas government and stability since 2014. The United Nations Security Council last week placed global restrictions on doing business with him. Badi is a senior commander of the armed Al-Sumoud Brigade and the Fajr Libya brigade, both of which have challenged the shaky UN-backed coalition Government of National Accord (GNA). "In August 2018, Badi ordered action against rival militias aligned with the GNA, exacerbating instability in Tripoli," the State Department said in a statement. "In addition, forces under Badis command have used Grad rockets in highly populated areas, causing indiscriminate destruction and casualties, including emergency responders and ambulance workers." The State Department said Badi had also been placed under financial sanctions by the UN Security Council’s Libya Sanctions Committee, and the listing requires all UN members to impose an asset freeze and travel ban. “Salah Badi’s prolonged militia attacks on Libya’s capital have devastated the city and disrupted the peace,” said Sigal Mandelker, Treasury undersecretary for terrorism and financial intelligence. During September, according to the US Treasury, which administers sanctions, Badis fighters ignored UN calls to join a ceasefire and continued attacking rival militias. Libya’s health ministry said late in September that at least 115 people were killed and 383 wounded in month-long clashes between rival factions in Tripoli. The GNA also blamed Badi, along with another militia leader, for a May 2017 attack in Tripoli. The Treasury said Badi played a critical role in battles in 2014 that nearly destroyed Tripoli’s main international airport and forced many people from their homes. The UN Security Council placed Badi on its sanctions list on Friday in response to a proposal by France. That came after key Libyan power brokers attended a contentious international effort to create the foundations for peace last week in Palermo, Italy.
