Bullet-ridden bunkers and signposts shredded by rockets bear witness to dozens of Taliban attacks this month on police posts around Kunduz, the northern Afghan city that fell briefly in September in the insurgents' biggest victory to date. Unlike that short yet humiliating blow to Afghan security forces and the NATO troops deployed to support them, this time the main checkpoints held firm, in a sign that some lessons of the recent past have been learned. "Last year the army didn't do anything and Taliban infiltration into the city took us by surprise," said police major Abdul Wahab. Now, he said, the army, police and Afghan intelligence were working closely together. While his comments reflect recriminations that flew between different branches of Afghanistan's fledgling security forces immediately after the fall of Kunduz, the fact that police and soldiers are coordinating closely is a significant shift. Reinforcements of regular Afghan soldiers and commandos have been sent to the area, an acknowledgement by the government in Kabul that holding on to the city should be a priority. As part of a new strategy to go after the enemy rather than wait for militants to strike first, Afghan army commandos have carried out at least 10 operations against them around the city since mid-March, and more are planned. "Last year Afghan forces learned that sitting back and being defensive is not working," said US Army Colonel Paul Kreis, top NATO adviser to acting Defense Minister Masoom Stanekzai. "This time they are being more maneuverable, more on the offensive," he said on a recent visit to the city. Taliban fighters bent on overthrowing the government still surround much of the city and say they have delayed an all-out assault in order to minimize civilian casualties. — Reuters
