A West Virginia airport terminal was evacuated Thursday after a female passenger's water bottle twice tested positive for explosives, a Transportation Security Administration spokeswoman said. Security checkpoint screeners got a positive test on a machine that uses swabs to find traces of explosives, TSA spokeswoman Amy von Walter said. A bomb-sniffing dog also reacted to the water bottle. "The bomb squad is on site and the woman is being interviewed by the FBI," von Walter said. Commercial airline service was temporarily suspended, and about 100 passengers and airport employees were ordered to leave the terminal, Tri-State Airport authority President Jim Booton said.
