08:52 AM EDT, 06/10/2026 (MT Newswires) -- US equity futures were edging lower pre-bell Wednesday as the US and Iran once again exchanged attacks after a US Army Apache helicopter was shot down, raising tensions in the Middle East.

Dow Jones Industrial Average futures were 0.6% lower, S&P 500 futures were down 0.6%, and Nasdaq futures were 0.7% lower.

US Central Command said in an X post that it launched "self-defense strikes" against Iran as a "proportional response to unjustified Iranian aggression," responding to the downing of a US Army helicopter. Iran, which did not claim responsibility for shooting down the chopper, responded with attacks on Bahrain, Kuwait, and Jordan.

In a post on Truth Social, US President Donald Trump said that Iran has been "completely defeated." Trump added, "They've taken too long to negotiate a deal that would have been great for them, now they will have to pay the price!!!"
