Amid fears of new violence, police will be on high alert around a Paris labor protest authorized under a tense compromise between unions and the government.

Unions are holding a short march Thursday around the Bastille plaza to protest government plans to make workweeks longer and layoffs easier. Similar protests against the legislation in recent months have degenerated into clashes between riot police and radicals.

Police threatened to ban Thursday's march, but the government agreed to let it proceed. Interior Minister Bernard Cazeneuve warned that "no violence will be tolerated."

Police have said some union members participated in and cheered recent violence. But the head of the influential CGT union, Philippe Martinez, insisted on BFM television Thursday that "We are not accomplices of the troublemakers. We condemn them firmly."
