PARIS — With French officials saying confidently on Saturday that an advance by Islamist militants on Bamako, Mali’s capital, had been halted, France’s foreign minister told African leaders that “our African friends need to take the lead” in a multilateral military intervention in Mali.

The foreign minister, Laurent Fabius, spoke in Abidjan, Ivory Coast, at a summit meeting to discuss how to accelerate the involvement of West African troops in Mali, although he acknowledged that it could be weeks before they were there in force.

“Step by step, I think it’s a question from what I heard this morning of some days, some weeks,” said Mr. Fabius, referring to the time frame when the bulk of troops from the Economic Community of West African States, the regional group known as Ecowas, would arrive.

On Sunday, Mr. Fabius told Europe 1 radio that Russia, which has previously remained on the sidelines of the conflict, had suggested helping France transport soldiers and equipment to Mali. He did not say whether France had accepted the offer.
