US House votes to halt Iran war, in rebuke to Trump

The US House of Representatives passed a measure that seeks to halt President Donald Trump from further military action in Iran.

The 215-208 vote was successful after four Republicans joined Democrats in a rare public show of disapproval of the war, which began in February. This is the fourth attempt by the House to rein in Trump's war powers, which critics say lack congressional approval.

Despite a ceasefire agreement, both the US and Iran have exchanged strikes in recent days. Ahead of the vote, Trump again asserted that negotiations to end the war are going "very well" and could be finalised this weekend.

The House resolution still needs approval from the Republican-controlled US Senate.

Republicans Thomas Massie, Brian Fitzpatrick, Tom Barrett, and Warren Davidson joined a united front from Democrats to pass Wednesday's resolution. Democrat Jared Golden of Maine, who had previously voted against similar measures, backed the measure.

The Senate has passed a similar resolution in May, but will need to take up this version advanced by the House. Even if it were successful in the Senate, the measure is unlikely to fully curb military action against Iran.

Trump could veto the measure, which would require a two-thirds majority in both chambers to nullify.
