KONNA, Mali, Jan 26 (Reuters) - French special forces were in action on Saturday at the Islamist rebel-held stronghold of Gao in northeast Mali, confronting "harassment" from rebel fighters, a French officer in Mali said on Saturday.
"The rebels have melted in to the local population. There is harassment. The operation is still under way. It is a bit complicated," the officer, who asked not to be named, told Reuters. French aircraft were providing air support. (Reporting Rich Valdmanis and David Lewis; Writing by Pascal Fletcher)
