PARIS/NEW YORK -- Former Malaysian Prime Minister Mahathir Mohamad sent out a series of tweets Thursday over the recent killing of a French teacher who used cartoons of the Prophet Muhammad in a classroom, writing that he believed in freedom of expression but that it should not be used to insult others.
One of his more controversial tweets said that Muslims have a right to "kill millions of French people for the massacres of the past." That tweet was later removed by Twitter on grounds that it violated the social media platform's rules.
