The US House of Representatives has approved a largely symbolic resolution seeking to limit President Donald Trump's ability to make war on Iran, BBC reports.
The measure passed the Democratic-run chamber 224-194, but faces an uphill climb in the Republican-held Senate.
It aims to mandate congressional approval for any conflict with Iran, except in cases of an imminent attack against the US.
Even if the House measure cleared Congress, it would not face a potential Trump veto because it is known as a concurrent resolution, which does not require a presidential signature.
