"Economic growth is expected to accelerate further during the new year, while inflation is projected to remain in mid-single digits," the bank said in a statement.

"It was decided at the meeting to take immediate action on several overdue urgent issues to enable the Northern Provincial Council to commence functioning smoothly to address the needs of the war affected people of the North and especially of its war widows, the displaced, the dispossessed, the war orphans, the long term PTA detainees, women headed households and other vulnerable sections of the Northern society."
