Oscar-winning Polish film director Andrzej Wajda has died aged 90, the Polish Filmmakers' Association has confirmed, BBC News reports.

He made more than 40 feature films in a career spanning 60 years.

Many of his films - including Kanal, Man of Marble, Man of Iron and Katyn - were inspired by Poland's turbulent wartime and communist history.

In 2000, Wajda was awarded an honorary Oscar for his contribution to world cinema.

Wajda's last film Powidoki (Afterimage) tells the life story of the avant-garde painter Wladyslaw Strzeminski, who suffered under the post-war Stalinist government in Poland.

The director said he wanted to "warn against state intervention in art".

The film was recently chosen as Poland's official entry for the best foreign language film at the 2017 Oscars.

Four of Wajda's earlier works had been nominated for that category. Man of Iron won the Palme d'Or at the Cannes Film Festival in 1981.
