Russia shipped units of S-300 anti-aircraft missiles from Syria to a Russian port near Crimea, according to an Israeli satellite imaging company, in an apparent attempt to bolster its air defences in its war with Ukraine.

ImageSat International (ISI) captured images showing the presence of the S-300 anti-aircraft battery at Masyaf, Syria in April, and the empty site left behind on August 25 after the systems were shipped to the port of Tartous.
