Britain is becoming more directly involved in the latest Middle East crisis, although the Government is stressing that the role is defensive rather than an attempt to join the fighting in Yemen.
Prime Minister Andy Burnham has agreed to a request from Saudi Arabia for British military assistance following renewed attacks by the Houthi movement in Yemen.
The first step will be the deployment of an RAF Voyager tanker to provide air-to-air refuelling for Saudi aircraft involved in defensive operations. The arrangement is expected to begin within days and initially last for several weeks, although the Government says it will keep the agreement under review.
That may sound like a relatively small military commitment, but it comes at a time when several conflicts and disputes are becoming linked through the world's energy and shipping networks.
What is the RAF actually doing?
An RAF Voyager is essentially a flying fuel station.
It can refuel fighter aircraft while they are in the air, allowing them to remain airborne for longer and cover greater distances. Britain is therefore not announcing that RAF fighter aircraft will be attacking Houthi positions.
The Government describes the assistance as defensive air-to-air refuelling for Saudi aircraft protecting the country from missiles and drones.
That distinction is important. The UK Foreign Office has condemned recent Houthi attacks on Saudi Arabia, including attacks on civilian and energy infrastructure, while also highlighting the danger to shipping through the Red Sea and Bab el-Mandeb.
Britain already has a military role in Saudi Arabia. Earlier this year the UK deployed its Sky Sabre air-defence system to help protect the country against missile threats from Iran. Britain and Saudi Arabia have also had a close defence relationship for decades.
Why has the situation suddenly become more important?
The Houthis control large parts of Yemen and have been fighting Yemen's internationally recognised government, which is backed by Saudi Arabia.
The conflict has now intensified again.
Houthi forces have advanced towards the Red Sea coast and seized important territory, including the port of Mocha and positions around the Bab el-Mandeb Strait. That is significant because Bab el-Mandeb is one of the world's major maritime chokepoints.
Around 12% of world trade normally passes through the waterway, according to Reuters and other reporting.
The Houthis have also attacked Saudi Arabia with drones and ballistic missiles, including an attack aimed at Riyadh.
For Saudi Arabia this is a direct security problem. For Britain and other countries it becomes an economic problem if shipping and oil supplies are disrupted.
And that is where British households come into the story
The Middle East may seem a long way from Caithness, but energy markets do not work that way.
Saudi Arabia is the world's largest oil exporter. The Gulf is also a major source of energy supplies moving into international markets.
The British Government says its involvement is partly about keeping important routes open. Burnham has linked the decision to protecting British interests and the wider region, including the movement of oil.
This matters because oil prices feed into the cost of petrol and diesel, transport, heating and many goods and services.
Britain is therefore dealing with a difficult combination. It wants to bring down the cost of living at home, but developments thousands of miles away can push up the cost of energy before they show up in household bills.
That is particularly relevant to rural households which depend heavily on petrol, diesel and heating oil.
Britain is not acting alone
Saudi Arabia has been seeking assistance from several countries as it faces the renewed Houthi threat. Britain is providing one particular capability rather than committing a large combat force.
The United States has so far taken a different approach, with reports that Washington has decided not to provide direct military support to Saudi Arabia in the latest fighting.
Britain is also involved in wider efforts to protect shipping. The UK-led Yemen Maritime Security Partnership includes Saudi Arabia, the United States, Japan, the European Union and other partners. The British Government says the partnership is intended to strengthen maritime security, disrupt weapons smuggling and protect freedom of navigation around Yemen and the Red Sea.
A small military deployment with a much bigger background
It would be easy to see the RAF Voyager announcement simply as Britain helping Saudi Arabia.
The wider story is more complicated.
The UK has longstanding defence and economic links with Saudi Arabia. The renewed Yemen conflict is taking place alongside wider instability involving Iran, the Gulf, the Red Sea and international shipping.
For Britain, the calculation is therefore not simply about Saudi Arabia's security. It is also about protecting international trade routes and trying to prevent another disruption to global energy markets.
For households in Scotland, the important question is what happens next.
If the fighting remains limited and oil and shipping routes continue to operate, the economic effect may remain relatively contained. If the conflict spreads or major shipping routes are seriously disrupted, however, the consequences could appear in fuel prices and eventually in the wider cost of living.
That is why an RAF tanker operating thousands of miles away can have a connection to the price of filling a car in Caithness.
