(CNN) -- At least seven people are dead and between 12 and 15 wounded in shootings at Fort Hood in Texas on Thursday, senior Pentagon official told CNN. At least one person is "neutralized" in connection with the incident, and a second is "cornered," retired Army Lt. Gen. Russel Honore told CNN, citing "unofficial, unconfirmed reports" from two sources. On the Fort Hood Web site, the word "closed" is posted with the statement, "Effective immediately, Fort Hood is closed. Organizations/units are instructed to execute a 100 percent accountability of all personnel." - Melanie Reed from Bookmarklet
