A large structure fire in downtown Old Town has damaged several buildings and forced the closure of two main streets.

The fire was reported just before 10 p.m. Saturday. WABI-TV reports crews found the building next to Yama's Bar and Grill fully engulfed when they arrived. Mutual aid was provided from many surrounding towns as the fire raged, damaging other surrounding buildings. Thanks to local resident, Bob Potts, for the video, that shows the scope of the fire. He told us that it's not unusual to hear sirens downtown but, when they just kept coming, he had to go investigate.

According to a post from the City of Old Town's Facebook page, portions of Main and Water Streets will be closed on Sunday. At this time, it appears no one was hurt in the blaze. Investigators from the Office of the State Fire Marshal will now work to determine how the fire started.

We'll update this story as more details become available.
