KUALA LUMPUR (Reuters) - Malaysia’s former premier Mahathir Mohamad said on Thursday Muslims have a right to “kill millions of French people for the massacres of the past” but he did not approve of the killing of a French teacher over his use of cartoons of the Prophet. In a blog post Mahathir, 95, a respected leader in the Muslim world, said he believed in freedom of expression but that it should not be used to insult others. “Muslims have a right to be angry and to kill millions of French people for the massacres of the past. But by and large the Muslims have not applied the ‘eye for an eye’ law. Muslims don’t. The French shouldn’t,” Mahathir said in a blog post, which he also posted on Twitter.
