The US stock market started the week with a disappointing performance as the tense conflict in Iran entered its fifth week.
The fall came as investors prepared to start a shorter trading week in conjunction with a public holiday.
In terms of the performance of the main indices, the Dow Jones fell 1.73% to 793.47 points, the S&P 500 fell 1.67% to 108.31 points, while the Nasdaq Composite plunged 2.15% to 459.72 points.
Investor doubts about the resolution of the Iran war are increasing after the Houthi militants joined the conflict.
The situation was driven by additional US troops deployed to the region.
