An explosion hit Beijing Capital International Airport's Terminal 3 on Saturday, with a man in a wheelchair apparently detonating a device.

Photos posted on China's version of Twitter, called Weibo, showed the man waving a white package in the air before the blast, which was heard at 6:24 p.m. local time.

Sky News Asia correspondent Mark Stone tweeted a photo of what is reportedly the moment the device was detonated.

Flights were not affected by the explosion and order has been restored to the airport.

Daily Telegraph correspondent Malcolm Moore posted on Twitter a photo of debris being cleaned up after the small blast.

He also said the bomb used was self-made from fireworks.

Sky News correspondent Stone also noted that a blog had been found, purportedly written by the blogger, which claims he was beaten up and paralyzed by Chinese police in 2005.

Airport police identified him as Ji Zhongxing, born in 1979 and from Shandong Province. He is more than likely one of millions of protesters who head to Beijing to petition for their social cause.

The airport's news office told the Associated Press that it was not aware of the explosion and airport police declined to answer questions.
