A supporter of Pakistan Tehreek-e-Insaf (PTI) political party leader Imran Khan holds a sign during a protest march against satirical French weekly newspaper Charlie Hebdo to the French Consulate in Karachi January 18, 2015. French President Francois Hollande said on Saturday that anti-Charlie Hebdo protesters in other countries do not understand France's attachment to freedom of speech. He was speaking a day after the satirical weekly's publication of a cartoon of the Prophet Mohammad sparked violent clashes, including deaths, in some Muslim countries.
