French President Emmanuel Macron came under pressure on Friday over what European leaders regarded as a 'bad debate' about the violence in Paris. Several of his counterparts tied the unrest to an explanation that Macron has flatly refused to discuss. At an EU summit, he tried to dampen the argument before it could become a wider confrontation over responsibility for the crisis. The exchange exposed a gap between Macron and some of Europe’s other governments. The disputed explanation was not specified, but he was resisting calls to address it directly. By Friday, efforts to control the discussion had themselves become a source of tension at the summit.
