BEIJING - Reports in foreign media of an explosion on board China's Liaoning aircraft carrier did "not conform with the facts", Defense Ministry spokesman Yang Yujun told a regular press conference Thursday.

Yang declined to answer questions about the construction of new aircraft carriers.

"As for the development and construction of China's new aircraft carriers, I have no further information to offer," Yang said.

China's aircraft carrier, the 300-meter Liaoning, was commissioned in September 2012.
