Several passengers onboard the United Airlines flight UA613 sustained injury as the aircraft made an emergency return to Lagos. The Washington bound flight with 245 passengers, eight flight attendants and three pilots made direct return to the Murtala Muhammed International Airport,

The same United Airlines aircraft had a similar issue earlier this week, with a rapid altitude drop prompting a diversion.

The Washington, DC-bound widebody jet - operating as flight UA613 - reportedly dropped about 200ft, according to accounts posted on social media.
