"The same members are killing or executing or celebrating over dead bodies, at the same time they are humanitarian heroes, and now they have an Oscar as you know," Assad said.
One of the most controversial decisions at this year's Oscar ceremony was the fact that The White Helmets, a movie produced by digital giant Netflix, won Best Documentary Short. For the company, it was their first-ever Oscar at the prestigious ceremony.
The Russian Defense Ministry has repeatedly raised the issue of White Helmets' controversial activity in Syria.
