Asia-Pacific markets plunged Monday, after the United States’ attack on three nuclear sites in Iran raised oil prices and investors’ fears of an escalation in the Middle East conflict.

Oil prices have spiked in recent weeks following the increased tensions in the Middle East.

Brent Crude was trading at $79.06 per barrel after surging 2.62%, as of 8.10 a.m. Singapore time, while the West Texas Intermediate crude added 2.75% to $75.89.

Over in Australia, the S&P/ASX 200 started the day 0.49% lower.

Futures for Hong Kong’s Hang Seng index stood at 23,396, pointing to a weaker open compared to the HSI’s last close of 23,530.48.

U.S. equity futures fell in early Asia hours following the U.S. strikes in Iran. Futures tied to the Dow Jones Industrial Average fell by 109 points, or 0.3%. S&P 500 futures shed 0.3% and Nasdaq 100 futures lost 0.4%.
