Around a dozen French tanks have deployed at Bangui's airport as intense gunfire in adjoining neighbourhoods sowed panic among residents, an AFP journalist reports.
The tanks took positions late on Wednesday afternoon at the entrance to the airport, where French and African peacekeepers are based, after automatic weapons fire and explosions shook several parts of the city.
Tens of thousands of people have taken refuge on the airport grounds since sectarian bloodletting erupted early this month in the former French colony, claiming hundreds of lives.
The heavy machine gun fire was apparently not directed at the airport but was especially intense in the nearby PK12 area.
Hundreds of panicked residents could be seen fleeing the area towards central Bangui, which was virtually deserted because of regular outbursts of gunfire in other areas throughout the day.
Peacekeeping troops were also absent from the streets, with only one helicopter, probably French, circling above.
Earlier Wednesday, a spokesman for the African peacekeeping force MISCA said its Chadian troops would be redeployed out of the capital amid charges they were siding with a former rebel group.
"The whole Chadian contingent will be sent to secure the north in the next few days," MISCA spokesman Lieutenant Colonel Ndong Toutoune told AFP.
The spokesman did not elaborate on how or exactly where the Chadian troops would redeploy in the impoverished country that has for decades been prone to coups, rebellions and mutinies.
The Chadians, mainly because they are Muslim, face accusations by many in Bangui of complicity with the mostly Muslim Seleka rebels who overthrew president Francois Bozize in March in the predominantly Christian country.
Amnesty International says some 1000 people have been killed since December 5, mostly by Muslim ex-rebels but also in Christian reprisal attacks.
The head of the Burundian contingent in the African MISCA force told AFP his men were disarming former rebels on Monday when Chadian troops from MISCA threw a grenade and opened fire on them, prompting some Burundian elements to return fire, wounding three Chadians.
On Monday, Chadian soldiers had opened fire on hundreds of stone-throwing protesters, mostly Christians, killing one man and wounding around 40 others, three seriously.
Traditionally influential in the Central African Republic, neighbouring Chad is France's main partner in its efforts to re-establish peace in the country. It contributes 850 troops to the 3700-strong MISCA force.
But the growing defiance of Central Africans toward the Chadian contingent is complicating the task of the 1600 French troops deployed to the country since the beginning of December.
The deployment came after interim President Michel Djotodia officially disbanded Seleka, but some of its members went rogue, leading to months of killing, rape and pillaging -- and prompting Christians to form vigilante groups in response.
