“I have asked prefects to trigger a number of curfews for this evening,” he told reporters after an interministerial crisis meeting, Anadolu Agency reported.
“They will be partial, they may be much localized," he added.
Prefects will consult mayors and business representatives before determining restrictions aimed at protecting people and property.
“There is no question of placing all of Paris under curfew. That would make no sense,” Lecornu said.
He did not rule out a state of emergency if necessary, but said targeted curfews currently appeared more appropriate.
“My determination to restore order is total,” he said.
Lecornu also announced “a very significant, massive judicial operation starting today,” with nearly 200 investigators within the Paris police prefecture examining images and videos to identify suspects.
“First and foremost, those who caused the damage must pay,” he said.
For affected businesses, he announced a short-time work scheme beginning Tuesday and a dedicated support fund to address cash-flow needs.
“This is a measure to protect employment,” he said.
Lecornu also pledged discussions with political parties on campaign security and policing, and with unions on safeguarding demonstrations.
“Many people demonstrated peacefully last Saturday, and that must be said again,” he stressed.
