Article: The coverage of the events by the media came under scrutiny during the relay. Chinese media coverage of the torch relay has been distinct in a number of ways from coverage elsewhere. Western reporters in Beijing have described Chinese media coverage as partial and censored (for example when Chinese media did not broadcast Reporters Without Borders' disruption of the torch lighting ceremony), whereas Chinese netizens have in turn accused Western media coverage of being biased. The French newspaper Libération was criticised by the Chinese State press agency Xinhua for its allegedly biased reporting; Xinhua suggested that Libération needed "a stinging slap in the face" for having "insulted the Olympic flame" and "supported a handful of saboteurs".

Question: Which French newspaper was accused of being biased by Chinese State press agency Xinhua?
Libération
