Washington has demanded the release of the American, who has been identified as Raymond Allen Davis, saying he has diplomatic immunity and shot the armed Pakistanis in self-defense on January 27 in Lahore because they tried to rob him, something police also have said.
A third Pakistani died when he was allegedly hit by a car that rushed to the scene to help the U.S. official.
The killings in Lahore on January 27 added to already strong anti-U.S. sentiment in Pakistan. Islamist and nationalist commentators have portrayed the incident as an example of American brutality and called on the government -- often criticized for being to beholden to Washington -- to punish the man.
Davis faces potential murder charges, and his next court appearance is set for February 11.
What sort of work Davis does for the United States is a major issue because it could affect whether Pakistan accepts the U.S. assertion that he has diplomatic immunity.
