EATTLE (AP) — Authorities say a natural gas leak that prompted an evacuation of the terminal at King County International Airport-Boeing Field has been secured and flights were scheduled to resume Friday evening. The Seattle Fire Department said Friday afternoon that crews had confirmed dangerous levels of natural gas within a commercial building in the 7000 block of Airport Way South. Fire crews established a perimeter of at least 1,000 feet in all directions. Seattle police said officers were helping with traffic control and that people should avoid the area. The Fire Department said just after 3:30 p.m. that Puget Sound Energy had secured the leak and that the area was being ventilated. No injuries were reported.
