President Donald Trump and his top officials are offering a string of fresh explanations for this week's U.S. military action in the Middle East.

Confronted by persistent questions about justifications, Trump says Iranian Gen. Qassem Soleimani and others were planning major attacks on four U.S. embassies.

But Trump and Secretary of State Mike Pompeo continue to rebuff questions about what they mean when they say those attacks were "imminent."

Meanwhile, Trump has ordered new economic sanctions against Iran, targeting senior Iranian officials and important sectors of an economy that is already straining under previous sanctions.
