Boeing's crisis-hit 737 Max jetliner faces a new potential safety issue as debris has been found in the fuel tanks of several new planes which were in storage, awaiting delivery to airlines.
A Boeing spokesman said the company did not see the issue further delaying the jet's return to service.
The aircraft has been grounded by regulators around the world since March 2019.
It was banned from flying after two separate crashes killed 346 people.
