Iran supplied components of heavy weaponry to Russia, directly breaching the resolution of UN Security Council No.2231, according to German paper Welt Am Sonntag.
The UNSC prohibits any supplies and servicing of heavy offensive weaponry.
intelligence agencies found out in June that two Iranian aircraft landed at
Khmeymim air base, the key air base of the Russian military in Syria. They
carried the equipment involved in construction of heavy weaponry, which then
was shipped further to Novorossiysk in Russia.
The outlet enclosed a photo of the Iranian plane at Khmeymim air base, without specifying when the photo was taken.
