Iran continues to worry investors

U.S. markets are poised to drop again today amid further fallout from President Trump’s order to kill a top Iranian general last week. Expect more turmoil.

Iran said yesterday that it was all but abandoning the 2015 deal to keep limits on its nuclear production, the biggest response yet to the American killing of Maj. Gen. Qassim Suleimani, the leader of the elite Quds force. Iraqi lawmakers also voted to oust the U.S. military from their country. Mr. Trump kept up his tough talk against Tehran and threatened sanctions against Baghdad.

How the markets are reacting:

• Brent crude oil jumped above $70 a barrel this morning, while gold hit its highest price since April 2013.

• Futures for the S&P 500, the Dow and the Nasdaq were down sharply, after the indexes fell on Friday.
