At least four crew were killed on Oct. 4, when a Ukrainian Antonov-12 cargo airplane made an emergency landing near the western airport of Lviv after disappearing from radar, officials said.

The Soviet-designed four-engine plane vanished from radar at 7:10 a.m. (local time) when it was 13.7 km (8.5 miles) from the airport, the emergency service said in a statement.

Officials said the military cargo plane carried a total of eight people. It added that “Burning is not observed,” and “the crew is being removed from the damaged aircraft.”

One of the crew had called the service at 7:29 a.m. to report the emergency landing of the plane, which was found 1.5 km (1 mile) from the airport.

The landing was made ‘in connection with the end of the fuel’, Ukrainian Infrastructure Minister Vladyslav Kryklii said later on Facebook, adding that the plane had been flying to Lviv from Spain.

The crew had scheduled to refuel in Lviv, Ukraine’s Unian news agency reported.
