SISSONVILLE, W.Va. (AP) — At least five homes went up in flames Tuesday afternoon and a badly burned section of Interstate 77 in West Virginia was closed after a natural gas line exploded in an hour-long inferno.

No injuries were immediately reported, but firefighters had just begun to reach damaged structures late in the afternoon after the intense flames kept them at bay for several hours.

Several people were treated for smoke inhalation, and a shelter was set up at Sissonville High School, where Gov. Earl Ray Tomblin planned a late-afternoon press conference
