Peter Jennings, the prime-time anchorman for ABC News in the United States, has died. He was 67. 

Mr Jennings announced in April that he had been diagnosed with lung cancer.

Born in Toronto on 29 July 1938, he won over America with his congenial and matter-of-fact style. He became a US citizen in 2003.

He had been with ABC television for more than 40 years, more than 20 of them as anchor of 'World News Tonight with Peter Jennings'. He covered seminal events from the Vietnam War and the civil rights movement of the 1960s to the 1989 collapse of the Berlin Wall and the 2003 invasion of Iraq.   

Mr Jennings had not been on the air since 5 April when, fighting back tears, he told stunned viewers he had lung cancer and needed time to fight the deadly disease.

He added he hoped to learn from almost 10 million cancer-stricken Americans 'how to cope with the facts of life that none of us anticipated'.

He underwent an aggressive chemotherapy treatment which resulted in significant weight loss and made his voice hoarse.

Mr Jennings was a former smoker who quit in 1988 but had a relapse in the aftermath of the 11 September 2001 terrorist attacks, when he admitted he needed something to alleviate tension that came with his job.

His passing completes a generational change in the news divisions of all three major US television networks.  

NBC's Tom Brokaw retired in December while Dan Rather of the CBS Evening News departed in March amid a scandal triggered by broadcasting an error-riddled story about President George W Bush's service in the National Guard during the Vietnam War.
