Two American service members were killed in an apparent insider attack in Afghanistan on Monday, a U.S. official told Fox News.

NATO's Resolute Support mission said in a news release the two U.S. troops were killed Monday. The U.S. official told Fox News an Afghan soldier killed the two Americans in Kandahar Province, located in southern Afghanistan.

The two service members were paratroopers from the 82nd Airborne Division, according to officials.

The commanding officer of the 3rd Brigade Combat Team, 82nd Airborne Division, announced the deaths on Facebook.

"It is with a heavy heart that I inform you of the loss of two paratroopers from the brigade during combat operations," Col. Art Sellers wrote.

"I ask you to respect the official Department of Defense notification process, a process which may take a few days. If you receive any information about these combat operations, either factual or speculative, I ask you to refrain from sharing it for the sake of the paratroopers’ loved ones."

NATO said in accordance with U.S. Department of Defense policy, the name of the service members killed in action are being withheld until 24 hours after notification of next of kin is complete.

The deaths mark the 11th and 12th U.S. service members killed in Afghanistan this year -- a number nearly equal to the 13 U.S. troops killed all of last year, according to the Department of Defense. In 2010 there were over 100,000 U.S. troops serving in Afghanistan and 437 soldiers were killed in combat.

The recent killings come after eight rounds of U.S.-led peace talks with the Taliban in Qatar.

Earlier on Monday, Secretary of State Mike Pompeo said President Trump ordered him to reduce the number of American troops in Afghanistan by the 2020 election.

“That’s my directive from the President of the United States. He’s been unambiguous: End the endless wars. Draw down. Reduce. It won’t just be us,” Pompeo said at the Economic Club of Washington, D.C.

The secretary of state has previously given September 1st as a deadline for the talks.
