The UN has accused Ukraine of defying an international embargo on South Sudan and supply it with weapons using Uganda as base

A UN panel of experts monitoring compliance with the embargo report pins Ukraine for supplying weapons responsible for the unrest in the youngest nation.

The report cites an Ilyunshinil-76 aircraft that left Kharkiv airport in Ukraine, bound for Gulu, Uganda on January 27.

It said the plane’s manifest indicated that it contained two L-39 jets and engines provided by Musket OU, a company based in Tallinn, operated by the Ukranian ministry of defense

In comes Uganda

“The Ukrainian Government confirmed that the two jets were listed as being operated by the Ugandan military and that the end user certificates indicated they were to be used only for pilot training,” the report read.

The experts said they were investigating if the planes were taken to South Sudan following reports that an aircraft with obscure markings was parked at Juba airport.

The panel said it was also investigating Hungarian fighter jet pilot — Tibor Czingali — contracted by the Ugandan Air Force, but believed to be flying South Sudanese aircraft.

The experts said they recently received documents from a confidential source that detailed a contract, signed in June 2014 by two National Security Service officers for a company based in the Seychelles to provide weapons to the South Sudanese Internal Security Bureau, headed by Akol Koor.

“Among the weapons are: 30 T-55 tanks, 20 ZU-23 anti-aircraft weapons, 5,000 rounds of T-55 tank ammunition, 10 BM-21 “Grad” rocket systems, 10,000 122-mm M21OF rockets, 3,000 S8 rockets for Russian-made Mi-24 attack helicopters, 20 million rounds of 7.62X39mm ammunition, 50, 000 AK-47 assault rifles and 12,000 RPG-7 rounds.

The report noted that border areas between South Sudan, Sudan and Uganda as key entry points for arms to Juba.
