ANNOUNCER: This is CNN breaking news.</s>COSTELLO: Some disturbing and tragic news out of Afghanistan this morning.</s>COSTELLO (voice-over): Officials now say American troops were killed in that suicide bomb attack in the Bagram District of Afghanistan. Barbara Starr is with me now, she has more from the Pentagob. Hi, Barbara.</s>BARBARA STARR, CNN CORRESPONDENT (voice-over): Good morning, Carol. The Pentagon is acknowledging that six service members from the mission in Afghanistan were killed. This was a mission that included U.S. personnel and Afghan personnel. All they're able to say officially is that six service members were killed. They do believe that Americans were amongst the killed, but they're not able to say yet whether all six were Americans. Three also injured. This happened outside of Bagram air base which is the major U.S. NATO base in northeastern Afghanistan. Apparently the troops were on a mission to hold some sort of meeting, we're told, with local Afghans. This was a suicide car bomb. Obviously, a very major attack. Six killed and still waiting for the official word on whether all of those who perished were American troops. Very difficult news, obviously, at this holiday season. Right now Afghanistan has just under 10,000 U.S. troops there. They will remain there through all of 2016. The Taliban very definitely showing their effort to launch attacks here. Also in northern Afghanistan and in the south, in Helmand Province, reports that the Taliban again are able to take over some small areas down in that part of the country. Carol?</s>COSTELLO (on camera): All right, I know you're still gathering information for us, Barbara, so I'll let you go. Thanks so much. The next hour of CNN NEWSROOM after a break.
