SAN JUAN, Puerto Rico (AP) — Nearly a dozen officers were injured in the French Caribbean island of Martinique during a fresh round of violent protests over the high cost of living, with demonstrators burning cars, looting businesses and targeting police, authorities said Tuesday.

The violence erupted late Monday in the capital of Fort-de-France, where protesters threw bottles and rocks and police responded with tear gas, according to a government statement. Some demonstrators also opened fire, officials said.

Meanwhile, a local union said several demonstrators were injured.

It is the latest in a string of protests that began in early September, prompting France to send special anti-riot police to the island, which has banned demonstrations in certain areas.

Martinique’s government said another meeting with citizens is planned for Thursday to talk about how to achieve sustainable prices for basic goods.

Martinique has seen similar protests in recent years, many of them fueled by anger over what demonstrators say is economic, social and racial inequality.
