Until now, no Russian military vessels had been spotted at Tartous since the fall of Assad regime in early December. In earlier high-resolution satellite imagery dozens of military vehicles could be seen parked near where the vessels are now docked. Also nearby were cranes which may be used to load equipment.
It is possible that two other Russian naval vessels are also present in the port, naval analyst Frederik Van Lokeren told BBC Verify. He said the vessels, Ivan Gren and the Alexander Otrakovsky, could also be involved in an evacuation – a sentiment echoed by Ukrainian military intelligence to BBC Verify.
“With the 49 year lease being cancelled it has become very clear for Russia that it can no longer hope to maintain a military presence in Tartous and as such, there appears to be no point in staying there and delaying the maritime evacuation any longer,” Mr Van Lokeren added.
The evacuation of all of Russia’s equipment may take some though, according to Anton Mardasov from the Middle East Institute’s Syria programme.
“Over the years much more has been brought in there than these ships and vessels can take,” Mr Mardasov told BBC Verify.
Meanwhile, there has also been continued activity at the main Russian airbase in Syria, Hmeimim. Satellite images have shown large Russian aircraft being loaded with military equipment on various dates since the fall of the Assad regime.
