BAGRAM, Afghanistan (AP) -- Defense Secretary Ash Carter is in Afghanistan to assess the fragile security situation, amid reports of increased violence and a growing campaign by Islamic State loyalists to gain a foothold in the eastern part of the country.
Carter's visit comes as his top commander there, Gen. John Campbell, voiced concerns that foreign fighters from Syria and Iraq are joining with Afghans who have declared loyalty to IS in the east, near the Pakistan border.
Officials have been warning for some time that while the presence of IS has been small, it is attracting disaffected members of the Taliban. Campbell in an Associated Press interview said supporters of IS are trying to establish a regional base in Jalalabad.
Fueling those concerns is a new Pentagon report saying that the Taliban has been emboldened by the reduced U.S. military presence in Afghanistan and attacks increased this year.
Carter is planning to meet with his military commanders and troops. He is on a weeklong visit to the region, and spent the last two days in Iraq.
There are about 9,800 U.S. troops in Afghanistan, including some who are involved in counterterrorism missions.
In October, at the urgings of his military commanders, President Barack Obama announced that he would keep troops levels steady through most of next year. By the end of 2016, rather than draw down to a Kabul-only U.S. military presence of about 1,000 troops as previously planned, Obama decided the U.S. will maintain 5,500 troops in Kabul and Bagram.
The latest report on violence in the country said Obama's decision reflects the need to give Afghans more time to develop a credible army.
