Boeing's US aid 'hurting Airbus'

The European Union (EU) has claimed that US subsidies for American aircraft maker Boeing have cost Europe's Airbus $27bn (£13.4bn) in losses.

EU officials put forward that figure at the start of a World Trade Organization (WTO) hearing into Brussels' complaint that the US aid broke free trade rules.

The US has a parallel complaint to the WTO against EU help for Airbus.

Washington counters that Airbus has used billions of euros of European subsidies to boost its market share.
