President Donald Trump said the U.S. Navy is working to remove Iranian mines from the Strait of Hormuz, which is a critical chokepoint for global oil shipments.

It's disruption is raising economic concerns about the world.

Experts caution that clearing underwater explosives could take months, even with a fragile ceasefire in place after weeks of fighting between the United States and Iran, according to the Associated Press.

They warn that any future U.S. declaration that the route is secure may not be enough to reassure commercial shipping companies and insurers that the passage is safe again.

Roughly 20% of the world’s oil supply typically flows through the strait.
