Syrian asylum seekers hold a sign with a message for Britain's Prime Minister David Cameron as they occupy a footbridge at the ferry terminal in Calais, northern France, October 4, 2013. Some fifty migrants, a majority Syrian, including women and children, have occupied the footbridge since Wednesday as they ask for the right to leave France and travel to Britain in order to join family members.
