SEVARE, Mali — French forces met no resistance Wednesday in Kidal, the Islamists’ last major town, as the two-week-old mission scored another success in its effort to dislodge the Al Qaeda-linked militants from northern Mali.

The capture of Kidal came just days after French and Malian forces retook two other provincial capitals, Gao and Timbuktu, which also had been under harsh Islamic rule for nearly 10 months.
