From The Times:
Military officials at Fort Hood said in a statement on Thursday that the suspect, Naser Abdo, is not based there.
"At this time, there has been no incident at Fort Hood," said the statement, which was posted on the base's Facebook page. "We continue our diligence in keeping our force protection at appropriate levels."
The statement said Mr. Abdo had been arrested by police in the town of Killeen, to the south of the base.
The Killeen Daily Herald, citing local authorities, said Mr. Abdo was absent without leave from a different army facility, Fort Campbell in Kentucky, but that there were allegations he was planning an attack on Fort Hood.
Citing an unnamed law-enforcement official, CNN reported that "Islamic extremist literature" and a .40 caliber pistol had been found in Mr. Abdo's backpack and that in his hotel room he had a number of suspicious items: more than one battery-operated clock, Christmas lights, sugar, shrapnel, a pressure cooker, shotgun shells and six pounds of smokeless powder. The network did not elaborate on the type of powder and it was unclear if those items alone could be used to manufacture an explosive device.
