BBC journalist Sue Lloyd-Roberts has died in a London hospital where she was being treated for leukemia. She was 64.

Her husband, Nick Guthrie, said she died Tuesday evening.

Lloyds-Roberts received many honors for a series of investigative reports that frequently involved travel to conflict zones. She had reported from Syria, North Korea and many other countries.

She helped focus public awareness on social ills including female genital mutilation, people trafficking, and forced marriages.

Lloyd-Roberts had written extensively about her illness and her public search for a stem cell transplant donor. She received a transplant in July.

In her final blog entries she described excruciating pain and weakness but also the pleasure of having her children and husband read to her as she tried to rest.
