KONNA, Mali – French and Malian troops regained control of the airport and bridge of the crucial, northern city of Gao on Saturday, marking their biggest advance yet in their bid to oust al-Qaida-linked extremists who have controlled northern Mali for months, military officials said.

The move comes just two weeks after France launched its military offensive in support of the shaky, central government of this former French colony. It is unclear what kind of resistance French and Malian troops will face in the coming days.

The French military said in a statement on its website that their special forces, which had stormed in by land and by air, had come under fire from "several terrorist elements" that were later "destroyed."
