KABUL, Afghanistan — Taliban insurgents pressed government forces on several fronts on Friday, killing at least eight Afghan soldiers in three separate episodes.

The attacks continued a sudden pattern of intense assaults almost every day, in another sign that the traditional fighting season in Afghanistan, where most fighting would ordinarily have ended by November, has been prolonged this year, and is still continuing at a high tempo.

Friday’s attacks came just a day after three serious attacks around the country, including two in Kabul.

Most American and NATO troops have ceased combat operations, and the Taliban have boasted that this has given them an increased ability to assault Afghan government forces. Air support and medical evacuation missions run by the American-led coalition on behalf of Afghan forces have also greatly decreased in recent months.
