US diplomat Richard Holbrooke has died, ABC News and CNN are reporting. Holbrooke, who was President Obama's special envoy for Afghanistan and Pakistan, was 69.
Holbrooke had undergone surgery in recent days for a torn aorta after collapsing at a meeting with Secretary of State Hillary Clinton on Friday.
The feisty and sometimes abrasive diplomat -- whose forceful style earned him nicknames such as "The Bulldozer" or "Raging Bull -- was perhaps best known for helping broker the 1995 agreement that ended the war in Bosnia.
He served as ambassador to the United Nations during the Clinton administration. He also was ambassador to Germany from 1993 to 1994 and then assistant secretary of state for European affairs.
Holbrooke's career with the foreign service dates back to his posting in South Vietnam in 1962 and included time as a member of the US delegation to the Paris Peace Talks on Vietnam.
