A man in a wheelchair with a personal grievance has detonated a homemade bomb at Beijing international airport, causing a small explosion.
Ji Zhongxing, 34, from central Shandong province, was injured and taken to hospital.
Xinhua news agency said he detonated a bag containing gunpowder used in fireworks after being stopped from handing out leaflets.
No-one else was hurt in the blast, which filled part of the Terminal 3 arrivals hall with smoke.
The BBC reports an online microblog attributed to the man said the explosion was to protest at ill-treatment by police in 2005.
The incident occurred shortly before 6.30pm on Saturday near one of the arrival gates.
Xinhua showed several medical personnel providing emergency treatment.
Order has been restored at the airport and there was no disruption to flights.
