Some Brooklyn residents woke up to the sound of sirens after a massive manhole fire broke out in Williamsburg.

Fire officials say they were called to Conselyea Street and Graham Avenue just before 8 a.m.

Flames engulfed a large part of the street before smoke started to spread down the block.

Although remnants of the fire can be seen on the street, residents say everything appears to be back to normal.

It's still unclear what started the fire and whether there have been any power outages in the area.

Con Edison is still investigating.
