PARIS (REUTERS) - French President Emmanuel Macron warned his fellow European Union leaders on Thursday (March 26) that the coronavirus outbreak risked undoing the bloc's central pillars such as its no-border zone if they failed to show solidarity in this crisis, a diplomat said.

"What's at stake is the survival of the European project,"he told the 26 other leaders in a conference call, according to a French diplomat.

"The risk we are facing is the death of Schengen," Macron added, according to the same source.
