Oil prices rose further as the war extended into a fifth day, with experts signalling the impact of this could be felt at forecourts in the coming weeks.

Drivers in Dereham reported that “queues are mental” at forecourts in the town.
The Tesco Extra petrol station had to close on Wednesday afternoon after running out of fuel, with people flocking to the nearby BP and Morrisons garages.
One woman who lives in the town said: “The queue was halfway around the Morrisons car park, it was absolutely insane.
“It hasn’t stopped, the queue is mental.”
There have also been reports of shortages in King’s Lynn and Bradwell.
A spokeswoman for Tesco said: “A scheduled fuel delivery has now arrived at our Dereham filling station and we are able to provide customers with fuel as normal.
“We have good availability of all fuel grades, with regular deliveries to all our fuel stations.”
Drivers have been warned not to break their refuelling routine, as it takes time for higher wholesale costs to filter through to the pump.

“Pump prices are heading up – wholesale costs had been increasing even before the weekend’s strikes on Iran,” said Luke Bosdet, a spokesman for the AA.
“The fuel trade has reported some increased demand, which was expected, but drivers in general are heeding advice to stick to their usual refuelling routines.
“There’s no point wasting time, fuel and money queuing when drivers don’t need to.”
RAC head of policy Simon Williams said the impact of oil price rises should not be felt for at least a week.
Mr Williams said: “We really shouldn’t see a shock jump in prices at the pumps as wholesale fuel costs had only been rising gradually in recent weeks.”
He encouraged retailers not to increase the price of fuel that is already in forecourt tanks.
