WASHINGTON (AP) _ The Brazilian ambassador to the United States underwent surgery Friday to remove a blood clot in his brain.

Embassy spokesman Pedro Borio said Ambassador Paulo Tarso Flecha de Lima, 62, was rushed to Georgetown University Hospital about 8:30 a.m. after he complained of feeling ill.

The ambassador's physician, Dr. Charles Rackley, who is a professor at Georgetown's medical school, examined de Lima and determined that he was suffering from a cerebral hemorrhage, Borio said.

``He went through several tests this morning, including an angiogram. And doctors decided it was necessary for him to undergo surgery immediately,'' Borio said. ``He remained coherent and awake throughout the morning, answering questions during the examination.''

De Lima has been Brazil's ambassador to the United States since November 1993.
