Pulitzer Prize-winning journalist and war correspondent Peter Arnett has died at the age of 91, US media has reported.

Arnett won the international reporting prize in 1996 for his Vietnam War coverage at the Associated Press (AP). But he was also well known for his work at CNN, having become a household name while reporting on the first Gulf War.

His career spanned decades and covered several conflicts in countries including Iraq, Vietnam and El Salvador.

The New Zealand-born journalist died on Wednesday surrounded by family and friends in California, his son told reporters. He was receiving hospice care for prostate cancer.

Arnett first worked for AP as a wire-service correspondent in Vietnam, from 1962 until the war's end in 1975, often accompanying troops on missions.

In 1997, Arnett became the first Western journalist to interview Osama Bin Laden at a secret hideout in Afghanistan, a few years before the 11 September 2001 attacks on the US. Arnett later worked for NBC and was famously sacked by the broadcaster after giving an interview on Iraqi state television, in which he was seen as critical of US military strategy.

Born in 1934 in Riverton, New Zealand, Arnett later naturalised as an American citizen and had lived in southern California since 2014. His contributions to journalism and his fearless reporting style have set a standard for war correspondents everywhere.
