US Transport Secretary Sean Duffy has announced that nationwide flights stops have been removed in the United States, located after a defect that had stopped all flights.

Duffy said it will take time for air traffic to return to normality, while many passengers continue to remain blocked at airports.

Secretary of Homeland Security Markway Mullin made it known that the interruption was caused by a telecommunications problem, stressing that there is no evidence of cyberattack.

Officials have attributed the problem to older systems, warning that similar situations could be repeated without a complete review of them.

The break began about 9: 00 a.m. Friday and lasted about four hours. It was the biggest stop in US flights since it was imposed following the 11 September 2001 attacks, the BBC reported.
