MADRID — The Spanish capital is poised to extend its restrictions on movement to more neighborhoods due to a surge in new cases in other districts, despite an outcry from residents over discrimination.

Police on Monday deployed to 37 working-class neighborhoods that have seen 14-day transmission rates above 1,000 per 100,000 inhabitants. People are required to justify trips out of those neighborhoods.

Locals complained that the restrictions stigmatize the poor, who often live in more cramped conditions and rely on public transport to get to their jobs.

On Tuesday, 16 more districts exceeded that transmission rate threshold, and Madrid’s regional president, Isabel Díaz Ayuso, said the possibility of extending the restrictions was on the table.

Regional vice president Ignacio Aguado said officials are assessing whether health services can cope with the increased cases before deciding on restrictions. “Things aren’t going well,” he said.
