The eldest son of Syrian President Bashar Assad has finished in 528th position out of 615 contestants in the International Mathematical Olympiad in Rio de Janeiro.

Hafez Assad, who competed with a Syrian team that placed 56th overall, posed with his teammates next to a Syrian flag on Saturday in the closing ceremony of the 12-day event.

Security has been tight at the hotel where the competition was held, due to the presence of the 15-year-old.

In his sole interview at the event, printed by news portal O Globo on Monday, Hafez commented on the ongoing conflict in Syria.

"It is a war against the people. The population and the government are united against the invaders who are taking the country," he said.

"The conflict has lasted six years and I hope it is nearing its end."

The overall winners at this year's International Mathematical Olympiad were South Korea, followed by China, Vietnam and the U.S.

The first International Mathematical Olympiad was held in 1959, in Romania. Next year's tournament is also scheduled to take place there, in the country's second biggest city Cluj.
