Libyan weapons are spreading at “an alarming rate” to new territory in west Africa and the eastern Mediterranean including Syria and the Gaza Strip where they are fueling conflicts and increasing the arsenals of armed groups and terrorists, a U.N. panel said.

In a report to the U.N. Security Council circulated Tuesday, the panel said cases of illicit transfers from Libya in violation of a U.N. arms embargo that have been proven and are still under investigation involve more than 12 countries and include heavy and light weapons such as portable air defense systems, explosives, mines, and small arms and ammunition.

Since the uprising that ousted dictator Moammar Gadhafi in 2011, the panel said, “Libya has over the past two years become a significant and attractive source of weaponry in the region.”
