Swedish-led Provincial Reconstruction Team (PRT), which has been based in Mazar-e Sharif since about 2005 and responsible for four provinces including Sar-e Pol, established an office and some troops in the province. The Afghan National Security Forces (ANFS) began expanding in the last decade and slowly took over security from International Security Assistance Force (ISAF). The Afghanistan-Turkmenistan border is maintained by the Afghan Border Police (ABP) while law and order for the rest of the province is provided by the NATO-trained Afghan National Police (ANP).
