A French military spokesman in Paris, Col. Thierry Burkhard, said French troops reached the airport at Kidal, in the remote northeast of Mali, in an ongoing operation that is ongoing.
Haminy Maiga, a local official, told news agencies that French forces met no resistance when they arrived aboard four airplanes that landed late on Tuesday. France also sent helicopters, he said.
Kidal is the capital of a desert region of the same name. Secular Tuareg rebels claim to be in control of the town after Islamists fled. A newly formed Islamist splinter group that broke with the main Ansar Dine Islamist force also claims to have a power base there.
The new group calls itself the Islamic Movement for the Azawad and is led by Alghabass Ag Intalla, a prominent leader of the Tuareg ethnic group from the Kidal region who has said he wants to negotiate a settlement with the central government in Bamako, 800 miles to the southwest. Azawad is a Tuareg term for northern Mali.
Mali has been in turmoil since early 2012, when junior officers in the south staged a coup to protest the government’s tepid response to an uprising in the north by Tuareg separatists who were subsequently pushed to the side by Islamic extremists bent on imposing an extreme form of Shariah law.
Earlier this month, the Islamists suddenly advanced toward the capital, threatening to engulf the south, topple the weak central government and destabilize a vast area of northern Africa.
After a series of punishing French airstrikes in recent days, French and Malian troops launched a lightning campaign on the ground, entering the northern towns of Gao and Timbuktu as Islamist rebels seemed to melted away to far-flung hide-outs, possibly in the Kidal Province.
In Gao, groups of residents were reported on Tuesday to be hunting down suspected fighters who had not fled ahead of the French-Malian military forces who took control of the town over the weekend. Other residents expressed concern that Gao remained unsafe and was acutely short of food and fuel after a prolonged isolation.
“The city is free, but I think the areas close by are still dangerous,” said Mahamane Touré, a Gao resident reached by telephone from Bamako, the capital. “These guys are out there.”
Mr. Touré, who spent the evening watching soccer on television and listening to music with friends, said that although everyone was enjoying the new freedoms, the legacy of Islamist occupation was evident in the hardship of everyday life.
“The price of gasoline is almost double, and the price of food is very high,” Mr. Touré said. “There are still things in the market, but no one has any money and there is no aid.”
Reporters and photographers in Timbuktu, the storied desert oasis farther north that the French-Malian forces secured on Monday, saw looters pillaging shops and other businesses, with some saying the merchants were mainly Arabs, Mauritanians and Algerians who had supported the Islamist radicals who summarily executed, stoned and mutilated people they suspected of being nonbelievers during their 10-month occupation.
Alex Crawford, a television correspondent for Britain’s Sky News, said, “This is months and months of frustration and repression finally erupting.”
The rapidly shifting developments came less than three weeks into the military effort led by France, the former colonial power whose helicopters and warplanes began arriving here at the Malian government’s invitation on Jan. 11. Since then other West African countries have started to send troops. Britain is preparing to send more than 300 military trainers, and the United States is providing aerial cargo and refueling help.
In Washington, Pentagon officials said that as of Tuesday 17 sorties by United States Air Force C-17 cargo jets had flown 500 French troops and 390 tons of equipment into Bamako. In addition, there has been one aerial refueling operation by an American KC-135 tanker aircraft, which provided 33,000 pounds of fuel to several French warplanes, the officials said.
At the same time, a meeting of international donors was getting under way on Tuesday in Addis Ababa, Ethiopia, as part of an effort to provide more than $450 million in long-term financing for the military intervention in Mali.
The French-led effort has met surprisingly little resistance from the array of Islamist militias that occupied the northern part of Mali, an area about twice the size of Germany, in the spring of 2012 in the midst of a national political crisis.
It remains unclear how long the foreign military occupation will last. Most of the Islamist fighters have melted into the desert and could be regrouping to fight again.
In a bid to consolidate the gains, troops from Mali and neighboring Niger arrived Tuesday in the small town of Ansongo, about 50 miles south of Gao, one day after President François Hollande of France urged African countries to take a more prominent role in the operations.
Just as in Gao two days before, residents filled the streets there to greet the arrival of the African troops as they toured Ansongo and its environs.
“Everyone is very, very, very happy,” said Ibrahim Haidara, an Ansongo resident reached by phone. “They chanted, ‘Vive la France!’ and ‘Long live African armies!’ ”
But like his counterparts in Gao, he worried that the fighters might not have gone very far.
“They are in the bush. They are hiding,” he said. “One must be careful.”
