Afghan blast wounds 4 U.S. military members
(CNN) -- An explosion in southern Afghanistan has wounded four members of the U.S. military on patrol near the city of Kandahar, a coalition spokeswoman said.
A roadside bomb was used in the blast on Monday morning, according to Col. James Yonts with Combined Forces Command in Afghanistan.
The bomb hit a provisional reconstruction team (PRT), a group of 40 to 80 civilians and military specialists who help in rebuilding projects or provide security for aid workers.
"It is a sad thing when ... provincial reconstruction teams supporting ... (the) Afghan people are attacked by someone in this nature," Yonts said.
"PRT ... is here to support the Afghan people, they are not here as combat forces."
The wounded were evacuated to Kandahar Airfield, according to Yonts, who said one member of the team received serious injuries.
A military statement said the team was traveling in a convoy from Lashkar Gah to Kandahar when it was hit.
A coalition team has been assigned to investigate the explosion.
