China said Friday the risk of damage on Earth from a rocket which fell out of orbit after separating from Beijing's space station was "extremely low", after the United States warned it could crash down onto an inhabited area. Foreign ministry spokesman Wang Wenbin said "most of the components will be destroyed by ablation during the re-entry" into the atmosphere and "the probability of causing harm to aviation activities or people... on the ground is extremely low". ehl-rox/apj/axn
