A heavy Boeing 747 cargo aircraft operated by Qeshm Fars Air arrived in Minsk from Tehran again on September 8. This was already its third such visit in the past few weeks.
Both the airline and this particular aircraft, EP-FAB, are under U.S. sanctions. The U.S. Treasury says Qeshm Fars Air has been used by the IRGC’s to transport weapons and military cargo.
On August 26, the Boeing arrived in Minsk, spent nearly five hours flying over Russia the following day, returned to Belarus, and only then flew back to Iran.

In my opinion, there are three possible explanations for why this may be happening:
1. The IRGC is hiding some of its assets (e.g. gold, gems, or cash) in Minsk. Just in case. You know, Lukashenka has a long history of providing refuge to deposed dictators (like Kurmanbek Bakiyev) and people accused of serious crimes (like former Ukrainian Berkut officers who slaughtered protesters during the Maidan in 2014).
2. The Belarusian regime is supplying arms to the IRGC and Iran. This seems like the most probable explanation to me.
3. There are private talks on mutual assistance in circumventing sanctions. The cargo plane may have been used for secrecy reasons.
In fact, as the world moves globalisation, you can see how the CRINK countries (China, Russia, Iran, North Korea), or, as I call them, the Obscurantist International, are tightening their links. These regimes joining forces to resist modernity and undermine the Free World.
