Actor Omar Sharif, best known for his roles in classic films Lawrence of Arabia and Doctor Zhivago, has died aged 83. Egypt-born Sharif won two Golden Globe awards and an Oscar nomination for his role as Sherif Ali in David Lean's 1962 epic Lawrence of Arabia.

He won a further Golden Globe three years later for Doctor Zhivago. Earlier this year, his agent confirmed he had been diagnosed with Alzheimer's disease. His agent Steve Kenis said he suffered a heart attack on Friday afternoon in a hospital in Cairo.
