France deploys troops to Paris after riots as Le Pen gains on Macron

France is deploying troops to reinforce police in Paris following weekend riots, as the government introduces longer curfews and tougher measures to stop masked looters. The unrest has intensified political debate over social cohesion ahead of next year's presidential election. A new poll shows right-wing leader Marine Le Pen gaining ground on President Emmanuel Macron, with her National Rally party leading at 34-38 percent. Business owners near Place de la Republique criticized police for failing to protect stores, while authorities investigate an arson attack linked to an "ultra-left" suspect. Further protests are planned for Saturday, prompting Prime Minister Sébastien Lecornu to promise a "massive" security deployment. Macron faces criticism for continuing a state visit to Qatar, while political leaders clash over rioters' "ACAB" slogan and left-wing groups' role in the violence.
