US inflation rises more than expected - here's what is happening with prices

US inflation rose by more than expected in the year to September, according to official figures, in the final data release before the midterm elections next month.
The pace of price rises increased to 3.7%, up from 3.4% in the 12 months to August.
Inflation was above forecasts, driven by higher gasoline prices which have risen following disruption to Middle East energy supplies due to the US-Israel conflict with Iran.
