Britain has raised the threat level for UK forces and diplomats in Iraq and placed its personnel and their families in Saudi Arabia, Kuwait and Qatar on an increased state of alert, because of what sources say is a heightened security risk from Iran. Sky News cites a Whitehall source as saying that Britain believes there is an increased likelihood of Iran or its proxies taking action against British, US or other allied interests in the region in a way that can be plausibly denied so as to avoid triggering an all-out war. The targets would most likely be soft such as oil infrastructure or other civilian targets, the source said. The aim would be to cause disruption but not to do something that could be directly linked back to the regime and therefore trigger a hard US response. The goal would be to signal Iranian anger at renewed US sanctions on Iran, which are hurting, and to push for them to be eased.
