BOSTON—Two manholes exploded in downtown Boston on Thursday morning, pouring smoke into the streets, forcing the evacuation of two buildings, and sending one person to the hospital with burns, authorities said.
The explosions, which also shattered a window, were reported around 8:30 a.m. near the High Street and Federal Street area in the Financial District.
