A United Airlines flight from Lagos, Nigeria, to Washington D.C., experienced unexpected turbulence resulting in injuries to several passengers.
Thirty-eight people sustained injuries, with six requiring hospital treatment for what airline officials called 'minor' injuries.
Nigerian authorities, however, described some of the injuries as 'serious', adding to the concerns surrounding the incident.
United Airlines is cooperating with aviation authorities in both the US and Nigeria to determine the cause of the unexpected aircraft movement.
