Just sink it
The MV Alaed, a Russian-operated cargo vessel, is currently thought to be sailing through the North Sea after allegedly picking up a consignment of munitions and MI25 helicopters - known as "flying tanks" - from the Russian Baltic port of Kaliningrad.
Washington, which last week condemned Moscow for continuing to arm the Syrian regime, has asked British officials to help stop the Alaed delivering its alleged cargo by using sanctions legislation to force its London-based insurer to withdraw its cover.
Under the terms of the current European Union arms embargo against Syria, imposed in May last year, there is a ban on the "transfer or export" of arms and any related "brokering" services such as insurance. Withdrawal of a ship's insurance cover would make it difficult for it legally to dock elsewhere and could force it to return the cargo to port.
