U.N. experts say Libya has become a primary source of illicit weapons, including shoulder-fired missiles, which have been trafficked to at least 14 countries and are fueling conflicts on several continents, Rwanda’s U.N. envoy said on Monday.

Rwandan Ambassador Eugene Gasana, chair of the U.N. Security Council’s Libya sanctions committee, briefed the 15-member council on the final report of the independent panel of experts who monitor violations of the world body’s sanctions regime.

A U.N. arms embargo was imposed on Libya at the start of an uprising in 2011 that ousted leader Muammar Gaddafi. The fragile government is struggling to rein in dozens of militias that helped oust Gaddafi and now defy state authority.
