AKIPRESS.COM - The Afghan government controls less than 60 percent of the country, a U.S. watchdog agency reported on Wednesday, after security forces retreated from many strongholds last year, said Reuters.

Afghan soldiers and police, with the aid of thousands of foreign military advisers, are struggling to hold off a resurgent insurgency led by the Taliban, as well as other groups like Islamic State.

As of November, the government could only claim to control or influence 57 percent of Afghanistan's 407 districts, according to U.S. military estimates released by the Special Inspector General for Afghanistan Reconstruction (SIGAR), in a quarterly report to the U.S. Congress.

That represents a 15 percent decrease in territory held compared with the same time in 2015, the agency said in a report.

"The numbers of the Afghan security forces are decreasing, while both casualties and the number of districts under insurgent control or influence are increasing."

More than 10 percent of districts are under insurgent control or influence, while 33 percent are contested, according to the report.

Some of the most contested provinces include Uruzgan, with five of six districts under insurgent control or influence, and Helmand, with eight of its 14 districts under insurgent control or influence.

U.S. military officials say much of the loss of territory reflects a change in strategy, with Afghan forces abandoning many checkpoints and bases in order to consolidate and focus on the most threatened areas.

Insurgents tried at least eight times to capture provincial capitals, although each assault was eventually beaten off.

According to U.S. military estimates, the number of Afghans living under insurgent control or influence decreased slightly in recent months to about 2.5 million people.

But nearly a third of the country, or 9.2 million people, live in areas that are contested, according to SIGAR, leading to some of the highest civilian casualty rates the United Nations has ever recorded in Afghanistan.
