Three Britons and a South African have died in a plane crash near Dubai worldwide airport, according to the Emirati authorities.
Large amounts of traffic are being diverted to Dubai World Central, the city's second airport which is close to the Expo 2020 site.
The report said the small DA42 plane was owned by Flight Calibration Services Limited, a company based out of Shoreham Airport.
Dubai International Airport later told The Associated Press that the plane "was being used to calibrate the approach systems" at the airport.
The airport said it halted flights from 7.36pm until 8.22pm local time due to the crash.
The small plane, a diamond 43 owned by Honeywell, had four passengers on board, when it crashed due to a technical malfunction. "The relevant teams are on the scene", Dubai Media Office said.
A small plane involved in upgrading a runway at Dubai International Airport crashed Thursday night, killing four people and halting traffic at the world's busiest airport for international travel for almost an hour.
The last major aircraft incident in Dubai happened in August 2016, when an Emirates Boeing 777-300 crash landed after flying in from Thiruvananthapuram, India.

The plane was operated on behalf of Honeywell, a US-based multinational involved in engineering and aerospace systems. "We are deeply saddened by today's plane crash in Dubai, and our heartfelt condolences are with the victims' families", the firm said.
