WASHINGTON — The president’s special envoy for Afghanistan and Pakistan was described as being in critical condition Saturday after undergoing surgery on a torn aorta.

Richard Holbrooke, 69, was meeting with Secretary of State Hillary Clinton at the State Department on Friday when he suddenly collapsed and was rushed to nearby George Washington University Hospital.

His family as well as Clinton and several other senior administration officials have been with Holbrooke at the hospital.

Hospital officials referred all questions on Holbrooke’s condition to the State Department.

Earlier, a State Department spokesman said the surgery on Holbrooke’s aorta, a main artery connected to the heart, was completed Saturday morning.

President Obama early in his administration named Holbrooke special envoy for Afghanistan and Pakistan.
