DUBAI, United Arab Emirates — Muslims in the Middle East and beyond on Monday broadened their calls for boycotts of French products and protests, as a clash over depictions of the Prophet Muhammad and the limits of free speech intensified. Kuwaiti stores pulled French yogurts and bottles of sparkling water from their shelves, Qatar University canceled a French culture week, and calls to stay away from the Carrefour grocery store chain were trending on social media in Saudi Arabia and the United Arab Emirates.
