France and the African Union on Saturday announced plans to deploy several thousand more troops into embattled Central African Republic, as thousands of Christians fearing reprisal attacks sought refuge from the Muslim former rebels who now control the country after days of violence left nearly 400 people dead — and possibly more.

French armored personnel carriers and troops from an AU-backed peacekeeping mission roared at high speed down Bangui’s major roads, as families carrying palm fronds pushed coffins in carts on the road’s shoulder. In a sign of the mounting tensions, others walking briskly on the streets carried bow-and-arrows and machetes.

Concluding an aptly timed and long-planned conference on African security in Paris, President Francois Hollande said France was raising its deployment to 1,600 on Saturday — 400 more than first announced. Later, after a meeting of regional nations about Central African Republic, his office said that African Union nations agreed to increase their total deployment to 6,000 — up from about 2,500 now, and nearly double the projected rollout of 3,600 by year-end.

Amid new massacres on Thursday, U.N. Security Council adopted a resolution that allows for a more muscular international effort to quell months or unrest in the country. Troops from France, the country’s former colonial overseer, were patrolling roads in Bangui and fanning out into the troubled northwest on Saturday.

“This force is going to deploy as quickly as possible and everywhere there are risks for the population, with the African forces that are present — currently 2,500 soldiers,” Hollande said, referring to the increased French presence. “In what I believe will be a very short period we will be able to stop all exactions and massacres.”

In an interview with France-24 TV, Hollande specified the AU reinforcements would arrive “in the coming days.”

Word of the bigger deployments came as human rights groups continued the grisly business of counting and collecting bodies of those killed in recent massacres. The death toll in the capital from the recent fighting rose on Saturday to 394, said Antoine Mbao Bogo of the local Red Cross.

Meanwhile, Central African Republic’s president called on the former rebels who are now integrated into the national army to stay off the streets now being patrolled by French and regional forces. Presidential spokesman Guy Simplice Kodegue said those who violated the order would be punished.

Aid workers returned to the streets to collect bodies that had lay uncollected in the heat since Thursday, when Christian fighters known as the anti-balaka who oppose the country’s ruler descended on the capital in a coordinated attack on several mostly Muslim neighborhoods.

As families mourned their dead, others fled by the thousands to the few known safe places in the capital — the airport guarded by French troops and the grounds of a Catholic center run by the Salesians of Don Bosco. About 3,000 people had fled to the complex on Thursday when the fighting began and that number swelled to 12,000 by Saturday.
