BROOKLYN HEIGHTS - Officials say explosions in five Brooklyn Heights manholes caused subway delays and home evacuations Monday.
The underground fire occurred at about noon around Willow Place and knocked out power to a substation that serves trains on the 4 line. Subway service was fully restored by Monday night.
Residents say the explosions sounded like bombs and shook the walls. Some residents on nearby streets were temporarily evacuated from their homes because of a strong smell of gas.
National Grid workers are investigating the cause of the explosions.
