I was deeply saddened to learn overnight that we suffered casualties in Afghanistan. The two service members killed and the four who suffered injuries were with Afghan forces as part of our train, advise and assist mission. Some of our Afghan partners also died. Our service members were doing their part to help the Afghans secure their own country while protecting our homeland from those who would do us harm. On this difficult day, please keep their families, friends and teammates in your thoughts and prayers. We will honor their sacrifice by finishing our important mission in Afghanistan.
