We will not be deterred in our mission to protect our homeland and help Afghanistan secure its own future."Among those wounded in the Bagram blast, which was carried out by a suicide bomber with an explosive vest, were 16 other U.S. service members and one Polish soldier, the Pentagon said.

Perry's remains. Their trip made headlines after first-class passengers reportedly booed when Stewart Perry and his family were let off a plane early to catch a connecting flight.In his interview with Fox 40, Perry's father commended the Army and the government for their treatment of his son and his Family. Vice President Joe Biden was among the dignitaries who met the Family at Dover Air Force Base."We really appreciate what Vice President Biden did and his care," Stewart Perry said.
