Interior Minister Gérald Darmanin asks prefects to deploy police in front of all Catholic churches and Protestant temples. The "very high" level of the terrorist threat as well as the "persistence of international tensions" " require the maintenance of extreme vigilance" for the Easter holidays, writes the minister in a note sent Thursday.

Easter commemorates the resurrection of Christ for Christians, and is celebrated on Sunday by Catholics and Protestants, and on May 5 by the Orthodox.
