South Sudan’s presidential spokesman Ateny Wek Ateny said earlier that the cargo plane had carried 18 people when it had crashed shortly after taking off in the nation’s capital Juba. He also said that the aircraft was owned by the Allied Service airline.

The transport minister of South Sudan said that rescuers had found bodies of 36 victims of the plane crash, including crew members. The search operation is set to continue, he added.

The aircraft was carrying out an order for a UAE airline, according to the CEO of Tajikistan's Asia Airways company, under the code of which the aircraft was registered, said.

The plane was operated by the South Sudanese Allied Services Limited company under lease from Asia Airways. According to CEO Narzikul Hamraev, Asia Airways made an agreement to fly the plane under its code while carrying out orders for other airlines.

The cause of the crash remains unknown, Hamraev added. A special commission, including experts from all parties, has been created to investigate the crash, he said.

The An-12 cargo plane that crashed in South Sudan on Wednesday was not permitted to fly as it had not undergone maintenance, Antonov plane manufacturer’s press service said.

"According to the information of the Antonov State Company, An-12B…had no reason to carry out flights as it had not undergone the maintenance prescribed in the operational documentation," the company told RIA Novosti.

According to the company, the plane was assembled on February 26, 1971, in Uzbekistan’s Tashkent.
