Jan 3 (Reuters) - U.S. stock indexes were set to slide 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 flaring tensions sent prices of perceived safe-haven assets soaring, while threatening to derail a recent rally in stocks.
"The market is just on edge and is giving up a large portion of yesterday's gains," said Robert Pavlik, chief investment strategist and senior portfolio manager at SlateStone Wealth LLC in New York.
"There is a question of what this (air strike) is going to turn into and if it's going to be something long lasting."
