I know that the answer to the question "What event led to Paralympic games to be cancelled?" is in "In June 2008, the Beijing Games' Organizing Committee announced that the planned international torch relay for the Paralympic Games had been cancelled. The Committee stated that the relay was being cancelled to enable the Chinese government to "focus on the rescue and relief work" following the Sichuan earthquake.". Can you tell me what it is?
A:
Sichuan earthquake
