"There will not be a military solution alone to the Mali problem. Therefore political efforts must also be intensified," Guido Westerwelle said in a statement. "The discussions under African mediation must be urgently continued."
With foreign backing, Malian government forces went on the counter-attack on Friday against Islamists who control the west African country's desert north and have sparked international alarm with a push south towards the capital, Bamako.
