German diplomat Tom Koenigs said the Taliban insurgency is supported by foreign money, terror networks, and fighters coming from Pakistan.
Speaking to reporters after briefing the UN Security Council on July 26, Koenigs said that the Taliban has "to be answered by a series of measures, political as well as military."
Koenigs said that the Afghan government should focus on development and good governance.
Afghanistan has recently seen a sharp rise in violence, with insurgents stepping up their attacks.
A spokesman for the U.S.-led coalition said on July 25 that more than 600 suspected Taliban militants have been killed in Afghanistan in the past six weeks.
