WASHINGTON, May 7 (Xinhua) -- The Pentagon confirmed on Tuesday that one U.S. soldier has died in a non-combat related incident in Afghanistan.

The soldier, who was assigned to the 48th Infantry Brigade Combat Team, died on Monday in Nangarhar Province, east Afghanistan, of wounds sustained from a non-combat related incident, said the U.S. Defense Department in a statement.

The soldier was supporting Operation Freedom's Sentinel in Afghanistan, the statement added.

The Pentagon said that the incident was under investigation.

The U.S. military has seen multiple non-combat related deaths in Iraq and Syria in recent weeks. But reported deaths in Afghanistan were mostly engaged in combat operations.

Fighting between government forces and Taliban fighters often gets intense in spring as it is locally branded as the fighting season.

The United States maintained some 14,000 troops in Afghanistan, largely providing training missions to local Afghan forces while also conducting counterterrorism operations against terror groups such as Al Qaeda and the Islamic State.

The death toll of U.S. servicemen in Afghanistan has surpassed 2,400 since the United States invaded the Asian country in 2001.
