     WASHINGTON-A chaotic scene unfolded near the US Capitol (美国国会大厦) on Wednesday

after police  shot and killed an armed man in what authorities described as  a rush hour traffic stop that

turned deadly.

     US Capitol Police spokeswoman Sgt.Kim Schneider said the unidentified 35-year-old man sped

away in a white car  after being stopped a few blocks from the Capitol.The man drove the wrong way

down a street and crashed into a police car in a heavily guarded area about a block north of the Capitol

grounds, striking two officers with his car along the way, she said.

     Police then opened fire after seeing the man hold up his handgun and refuse to put it down, said

Schneider, who described the melee as "very fast moving". "The officers felt they were being

threatened-they were in fear for their lives, "Schneider said.

     She did not know if the man ever fired at police.He was taken to a hospital, where he was

pronounced dead.

     The officers who were hit-one of whom was on a motorcycle-had minor injuries, Schneider said.

     The late afternoon scare occurred as lawmakers were wrapping up a third day of hearings for

Supreme  Court nominee Sonia Sotomayor.Police briefly closed up part of the Capitol as a precaution,

but the buildings were reopened about a half-hour later.Authorities said the shooting was not related to

the Capitol.

     Carol Lanigan, of Toledo, Ohio, described how she saw a white car come flying down the street with

two police cars chasing it.She said she heard about four or five shots.

     "There were so many gunshots being fired, my family got down, "said Robert Drumm of Oklahoma,

who was touring the nation's capital with his family.
