SEVARE, Mali -- French forces took control of the airport and a key bridge in the radical Islamist stronghold of Gao under the cover of darkness early Saturday, marking a significant inroad into the heart of territory held by the al-Qaida-linked extremists.
The move comes just two weeks after France launched its military offensive to rout the Islamists from power in northern Mali. It is unclear what kind of resistance they will face in the coming days
French and Malian forces came under fire in the morning and continued to face sporadic "acts of harassment," in the afternoon, said Col. Thierry Burkhard, a French military spokesman in Paris. He had no immediate estimate on casualties.
The Islamists first seized control of Gao and two other northen provinicial capitals -- Timbuktu and Kidal -- in April last year during the chaotic aftermath of a coup in the distant capital.
French Defense Minister Jean-Yves Le Drian announced in a statement from his ministry Saturday that jihadist fighters who encountered the advancing French and Malian troops "saw their means of transport and their logistics sites destroyed."
Nouhoum Maiga, a deputy mayor in Gao, confirmed Saturday that the French had come by land and air late Friday.
Gao has been under the control of the al-Qaida-linked Movement for Oneness and Jihad, or MUJAO, for months.
On Friday in a show of might, the Islamist radicals destroyed a bridge near the Niger border with explosives, showing that the extremists still remain a nimble and daunting enemy.
Since France began its military operation two weeks ago with a barrage of airstrikes followed by a land assault, the Islamists have retreated from three cities in central Mali: Diabaly, Konna and Douentza.
The Islamists, though, have maintained control of the majority of the territory in Mali's north, most importantly the cities of Gao, Kidal and Timbuktu.
The announcement that Gao's airport had been taken marked the first official confirmation that French and Malian forces had reached the city. Previously the closest they had been was Hombori, a town some 155 miles (250 kilometers) away.
The French currently have about 2,500 forces in the country and have said that they will stay as long as needed in Mali, a former French colony. However, they have called for African nations to take the lead in fortifying the Malian army's efforts.
There are currently some 1,750 troops from neighboring African countries, including Togo, Nigeria, Burkina Faso, Benin, Senegal, Niger and Chad.
The French-led mission began after the Islamists surged the farthest south yet and took the town of Konna. On Saturday, the Malian military allowed international journalists to enter the town for the first time since the conflict began.
Residents described the civilian casualties that took place during the French air strikes, including one that left three women and a child dead. Officials have said at least 11 Malians died in the military effort to retake the town.
Souleymane Maiga said the women were preparing food in the courtyard underneath a mango tree when he heard the helicopters overhead.
"I ran and hid between the walls of our courtyard," he said. "After it was over, I went to the house and I opened the door and that's when I saw that they were dead."
Only a toddler survived, Maiga said.
"They were one on top of the other. The baby was crying," he said. "I tried to feel for a pulse to see if there was any life, but I found that they were all dead."
