PARIS — Tens of thousands of people marched in Paris on Sunday to protest rising living costs, amid an increasingly tense political atmosphere marked by strikes at oil refineries and nuclear plants that threaten to spread further.
The march had been planned long before the strikes by a coalition of left-wing parties eager to capitalize on the cost-of-living crisis and assert itself as the leading opposition force to President Emmanuel Macron. But on Sunday, organizers signaled that they intended to build momentum from the climate of social unrest to increase pressure on Mr. Macron’s government.
