Aug 9 (Reuters) - U.S. stock indexes looked set to open lower on Wednesday as investors shunned risky assets following escalating tensions between North Korea and the United States.
North Korea said it was considering plans to fire missiles at Guam, a U.S.-held Pacific island, after President Donald Trump on Tuesday warned the nuclear-armed nation that it would face "fire and fury" if it threatened the United States.
Safe-haven assets gained. Gold rose 1.2 percent, while the Swiss franc was on track to post its biggest single day rise in about two-and-a-half years.
U.S. stocks closed lower on Tuesday after Trump's comments sparked a late afternoon selling. The Dow snapped a nine-day streak of closing records.
The CBOE Volatility Index, the most widely followed barometer of expected near-term stock market volatility, closed at its highest in about a month.
European shares were also lower following reports that a car had rammed a group of soldiers in Paris, injuring six before speeding off in what officials identified as a suspected terrorist attack.
"The geopolitical tensions have prompted a risk off trade amid investors," said Naeem Aslam, chief market analyst at Think Markets UK.
"Trump's comments about North Korea have created nervousness and the fear is if the president really means what he said "fire and fury". The typical textbook trade is that investors rush for safe haven, hence we have experienced a bounce for the gold price."
