France's wartime past takes centre stage in presidential campaign
Far-right presidential candidate Marine Le Pen comes under pressure after her party replaces its leader for the second time in three days. Jean-François Jalkh, who was appointed on Tuesday, cast doubt back in 2000 over the use of Zyklon B gas in Nazi death camps. Meanwhile, Emmanuel Macron visited the town of Oradour-sur-Glane in central France, where 642 people were killed by SS troops in June 1944. The centrist candidate warned of the danger of Le Pen's victory, saying "nationalism is war".
