The price of petrol in the united states has risen after a key network of pipelines was shut in the wake of Hurricane Harvey.
This is sparking fears of a squeeze on fuel supplies to major US cities.
Reports say some East Coast refineries are running out of petrol and European traders are scrambling to provide additional supplies.
The hurricane has already forced the closure of nearly a quarter of US oil refining capacity and fuel prices have risen by more than 10 cents a gallon to nearly $2 and a half on average nationwide.
