Christian civilians fled by the thousands to the airport guarded by French forces in this chaotic capital Friday as the mostly Muslim armed fighters who have ruled the country since March hunted door to door for their enemies and the death toll from inter-communal violence increased to 280 people.

Bodies were decomposing along the roads in a capital too dangerous for many to collect the corpses. Thursday’s clashes marked the worst unrest in Bangui in nine months and raised fears that waves of retaliatory attacks could soon follow.

“They are slaughtering us like chickens,” said Appolinaire Donoboy, a Christian whose family remained in hiding.

France had pledged to increase its presence in its former colony well before Christian militias attacked the capital. The arrival of additional French troops and equipment came as the capital teetered on the brink of total anarchy and represented the greatest hope for many Central Africans.

As night fell across the near anarchic capital, Christians fearing retaliatory attacks by the mostly Muslim ex-rebels crowded as close to the runway as possible, laying out their woven mats in front of a barbed-wire coiled fence. National radio announced that at least 280 people had died, citing figures from local Red Cross officials.

The U.S. State Department said it was “deeply concerned” by the violence and praised France’s quick intervention.

France signaled its amped up presence in its former colony on Friday by sending out armored vehicles to patrol the streets. A French fighter jet made several flyovers, roaring through the sky over an otherwise lifeless capital as civilians cowered at home. Britain also flew in a C-17 plane Friday loaded with equipment to help with France’s intervention.

As many as 250 French troops are carrying out permanent patrols in Bangui, and “we didn’t notice any direct clashes between armed groups today,” French military spokesman Col. Gilles Jaron said in Paris.

“Thanks to France and the United Nations who want to save the Central Africans, soon the Seleka attacks on civilians will stop. We have had enough of Seleka killing, raping and stealing,” said Abel Nguerefara, who lives on the outskirts of Bangui.

Streets in the city were empty Friday except for military vehicles and the trucks favored by the rebel forces who now claim control of the government. Nine unclaimed bodies remained in front of the parliament building — local Red Cross workers didn’t dare retrieve them or other bodies that were left to decay outside.

Despite the cheers that went up when a jet engine roared overhead, France insisted it was going only reluctantly into Central African Republic and with the limited aim of doubling its presence in the country to 1,200 troops.

Rebel leader-turned-president Michel Djotodia appealed for calm, even as his residence and that of the prime minister were looted and vandalized by the fighters Thursday. He announced a dusk-to-dawn curfew in hopes of preventing retaliatory violence against Christians from Muslims.

In a speech broadcast Thursday in the Sango language and a television interview in French, Djotodia called on people to realize that French forces were not in Central African Republic to take sides in an increasingly sectarian conflict.

Djotodia, who is Muslim, unified rebel groups in the country’s mostly Muslim north, where resentment of the federal government and a sense of disenfranchisement has been rife for years. Yet once those rebels were unleashed on the capital, he wielded very little control over the mix of bush fighters, child soldiers and foreign mercenaries he had recruited.
