Guadeloupe’s prefect, Alexandre Rochatte, who represents the French government, said in a statement on Sunday that armed groups had tried to loot stores in Pointe-a-Pitre, Basse-Terre and Lamentin and battled police.
Shots were fired at police and firemen trying to put out blazes.
Four pharmacies were broken into and cars set on fire while barricades were erected to stop security forces from intervening, the prefect added.
Interior Minister Gerald Darmanin said on Saturday that France would send about 50 members of the GIGN and RAID elite tactical forces of the gendarmerie and police to the territory.
Prime Minister Jean Castex is also due to meet on Monday in Paris with Guadeloupe officials to discuss the situation.
Rochatte on Friday had imposed a curfew from 6 pm to 5 am following five days of civil unrest during which barricades burned in the streets and firefighters and doctors walked out on strike.
Fragile health system
The doctors’ union in Guadeloupe warned against further trouble while the health system was so “fragile”.
They criticised “individuals who may have prevented patients from getting access to treatment, or medical staff from reaching their place of practice”.
While most people in mainland France have now received two vaccination doses, rates in its overseas territories have lagged behind.
By November 16, some 46 percent of adults in Guadeloupe had received at least one jab of a vaccine against Covid-19.
