Jan 3 (Reuters) - U.S. stocks fell about 1% at the open on
Friday as investors moved away from riskier assets after a U.S.
air strike in Iraq killed a top Iranian commander, sharply
escalating geopolitical tensions in the Middle East.
Iran's Supreme Leader Ayatollah Ali Khamenei vowed harsh
revenge after Qassem Soleimani, head of Iran's elite Quds Force,
was killed in the air strike in Baghdad that was authorized by
President Donald Trump. The Dow Jones Industrial Average .DJI fell 315.47 points,
or 1.09%, at the open to 28,553.33. The S&P 500 .SPX opened
lower by 31.49 points, or 0.97%, at 3,226.36, while the Nasdaq
Composite .IXIC dropped 115.76 points, or 1.27%, to 8,976.43
at the opening bell.
