Investigation by experts showed that the fire was caused by gasoline while the bus used diesel engine.

A government official said that the case was initially identified as a “serious criminal case” and further investigation was under way, state-run Xinhua news agency said.

A working team led by State Councilor and Public Security Minister Guo Shengkun arrived in Xiamen today.

After inspecting the scene and comforting the injured in hospitals, Guo has asked experienced medical staff to expedite the rescue of injured and ensure best treatment for all of them.

The Public Security Ministry has urged local police departments to take rapid and effective measures to carry out a safety overhaul and ensure overall social stability.
