Kenya's aviation authority (KCAA) has explained what caused diversions and delays at the country's main international airport in the capital, Nairobi.
In a statement, the KCAA claimed that "an Uninterrupted Power Supply unit for the Radar... encountered a fault. The Radar was turned off to allow for a replacement".
Operations were disrupted for 95 minutes to make sure that passengers were safe, it adds.
Two flights were diverted and 15 were put in a holding pattern in the air while the problem was sorted out.
