WASHINGTON, July 23 (Reuters) – The Republican-led U.S. House of Representatives backed a resolution on Thursday directing President Donald Trump to halt U.S. military action against Iran unless he obtains ​Congress’ approval, but the Senate voted hours later to block ‌a separate, similar measure.

The House vote, the latest rebuke of Trump from Congress, was 214-208 in favor of the war powers resolution as four Republicans joined Democrats in voting for it.

But the Senate voted 49 to 47 to block its own war ‌powers measure ​within hours of the House vote.

The House ⁠resolution, introduced by Representative Pramila ⁠Jayapal, a Washington Democrat, directed Trump “to remove the use of United States Armed Forces from hostilities” against Iran unless Congress authorizes it. However, it was largely symbolic. Lawmakers have passed similar resolutions repeatedly in ​recent months, but they have not led to a cessation of the war.

The four House Republicans who voted in favor were Tom Barrett ⁠of Michigan, Brian Fitzpatrick of Pennsylvania, Warren ⁠Davidson of Ohio and Thomas Massie of Kentucky.

In the ​Senate procedural vote, Republican Susan Collins of Maine voted with Democrats in favor ​of the resolution and Democrat John Fetterman of Pennsylvania voted ‌with Republicans against it. Four Senators did not vote.

Trump’s Republicans hold slim majorities in the House and Senate.

The votes reflected growing frustration among lawmakers of both parties about a conflict that Trump pitched as a quick, focused ⁠effort that would trigger Iran’s capitulation but instead has become a morass for the United States.

Trump recently announced a ramp-up in attacks on Iran, and ⁠the deaths of more ‌U.S. service members. Trump on Thursday promised “major military punishment” ⁠for Iran and its Houthi allies, after the ​Yemeni fighters ‌struck two Saudi oil tankers in the Red ​Sea, extending the ⁠Middle East war to a second major shipping chokepoint.

Additionally, two weeks since the effective collapse of an interim truce meant to end the war, the U.S. military launched another nightly round of airstrikes on Iran, prompting Iran to fire at U.S. bases in neighboring countries.
