PRIVATE security boss Erik Prince is facing UN sanctions over allegations he breached an arms embargo on Libya and planned to form a hit squad to take down opponents of General Khalifa Hiftar.

A confidential report to the UN security council, obtained by the New York Times and the Washington Post, alleged that the Trump ally organised a foreign mercenary force and shipped weapons to Gen Hiftar.

The general is trying to overthrow the UN-recognised Government of National Accord, headed by Fayez al-Serraj, to install rival body the Libyan House of Representatives.
