US spent $5.6bn on munitions in first two days of Iran war, Trump administration says

US President Donald Trump's administration said it used $5.6bn in munitions during the first two days of strikes against Iran in a report provided to US congressional committees, a source familiar with the information said on Tuesday.

Members of Congress have expressed concern that the conflict will deplete US military stocks at a time when the defence industry is already struggling to keep up with demand.
