The paper also voiced concern at what it called “verified reports” of rights violations by Afghan national security forces.
It highlighted an incident in Kunduz Province where it said a dozen people were beaten for supposedly supporting the insurgency.
“Pro-government armed groups, in full view of Afghan national security forces, carried out house-to-house searches, looting homes of mobile phones, cash, gold, jewelery, school materials, crops and livestock,” it said.
It also reiterated longstanding concerns about the Afghan Local Police, branded by critics as a thuggish militia.
The report said civilian casualties attributed to the police group tripled from 2012 to 121 last year, with 32 killed and 89 wounded.
It said most of these came from group members carrying out “summary executions, punishments and revenge actions.”
