Sadako Ogata, a high-profile Japanese diplomat who served as the first female United Nations High Commissioner for Refugees from 1991 to 2000, has died at 92, the government said Tuesday.

She died on Oct. 22, and a funeral was reportedly held at a church in Tokyo on Tuesday. The cause of her death was not immediately known.

News of the death of Ogata — known for her decisive, pragmatic leadership at the U.N. for years — immediately drew condolences from diplomatic and academic leaders across the world, including Prime Minister Shinzo Abe.
