A United Nations report says Afghanistan is witnessing "considerable political volatility and disconcerting levels of insecurity."
The report to the UN Security Council by Secretary-General Ban Ki-moon says Afghanistan saw a near 40-percent rise in the monthly average number of "security incidents" recorded for the year through to the end of August, compared with the same period of 2010.
The document said the volatile south and southeastern region bordering Pakistan remains "the focus of military activity," accounting for two-thirds of total security incidents.
The report also said the areas where security responsibility was handed over from international troops to Afghan security forces continue to face a "resilient insurgency that is attempting to challenge the capacity of Afghan forces to maintain security."
