The Pitié-Salpêtrière hospital in Paris has been at the centre of a major controversy after incidents that took place there in the aftermath of this year's annual May Day demonstrations. Throughout the evening of May 1st and into the following morning, several members of the government and senior health managers in Paris insisted the well-known hospital had been “attacked” by violent demonstrators. Yet in fact there was no such attack: instead, a few dozen protestors sought refuge in the hospital's buildings to escape police tear gas and charges. There was no threatening behaviour from protestors towards hospital staff and none of them damaged the premises. However, some were later hit by the police. Now interior minister Christophe Castaner has formally retracted his use of the word “attack”. Dan Israel reports.
