“Russia has been accused by Western diplomats of reneging on a pledge to stop supplying arms to the Syrian regime. The assurances made over a month ago were presented by British officials as a sign that the Kremlin was distancing itself from President Bashar al-Assad and his ruling coterie.
The flow of arms has, however, continued unhindered with the Russians stressing that there was no United Nations prohibition on supplies and it was simply fulfilling its contractual obligations. As well as air- and naval-defence systems, the Kremlin may now be preparing to send Yak-130 jets which can be fitted with missiles [for] ground attacks.
Western officials also claim that Moscow has refused to provide full details of the contractual obligations they have to fulfil and there is also evidence that the regime is getting further Russian arms through third parties.
