US aircraft manufacturer Boeing received at least $5.3bn (£3.3bn) in unfair aid from Washington, the World Trade Organization (WTO) has concluded.
The subsidies included money for research and development from the Nasa space agency, a panel of international trade judges has ruled. Last year the WTO said that Boeing's arch rival Airbus had received illegal aid from European governments.
