CRS wounded in the head during the clashes in Paris hospitalized in this hospital

According to Interior Minister Christophe Castaner, who visited the site in the late afternoon, the hospital was "attacked" by dozens of ultra-leftist black block anti-capitalist activists. Thirty people were arrested, a police officer told the minister during his visit.

The Pitié-Salpêtrière is located near the Place d'Italie, where the route of the trade union demonstration ended in a cloud of tear gas and after clashes. A CRS, wounded in the head during the clashes of the afternoon, had just been admitted to this establishment. However, Martin Hirsch could not say if these two elements were related, or if the intruders "were fleeing something". "I do not know the motivation for this inexplicable intrusion, I do not think there is a connection," he said. "We will be giving the police videos that make it easy to see and absolutely inspiring, and I did not see them screaming for a particular wounded person," he added.

Agnès Buzyn will visit on Thursday

Marie-Anne Ruder told France Inter that the intruders had forced the entrance gate of the establishment. When she arrived there, "dozens of people were entering the hospital compound." Among the intruders, there were people in "yellow vests", demonstrators in civilian clothes, and people with entirely masked faces, according to his story.

Health Minister Agnès Buzyn has announced that she will visit the site Thursday to show her support for the staff. "We would not like to believe it, we would like to say that violence can not target everything, and picking on a hospital is unspeakable," she commented on Twitter.
