Sept. 11 (UPI) -- Five U.S. troops were wounded in an apparent suicide bomb attack in Afghanistan Monday, the 16th anniversary of the 9/11 attacks that propelled the United States into a war still raging today.
The suicide bomber drove a car bomb into an armored convoy near the Bagram Air Base in northern Afghanistan, officials told Fox News.
The attack affected the NATO-led coalition, Operation Resolute Support, and at least one more troop from an undisclosed country was wounded in the bombing, as well.
"A small number of Resolute Support service members and Afghan civilians were wounded today when a suicide attacker targeted their convoy with a vehicle borne improvised explosive device near the village of Qal'eh-ye Musa Bala in Parwan Province," according to a statement released by the coalition, reported CNN.
The United States has led coalitions in Afghanistan since weeks after the 9/11 attacks and have remained ever since.
"Each of us will walk away from this simple ceremony reminded that the war is not over and that further sacrifice will be required," Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford said Monday during an event for the anniversary of the 9/11 attacks.
Estimates vary regarding the financial cost of the war in Afghanistan, but they range between $841 billion and $2 trillion.
