A fire on the second floor of a six-story building in the Bronx early Saturday morning left one person in critical condition and seven others injured, according to FDNY officials.

Just after 2:30 a.m., the Fire Department received a call about a potential fire in a partially residential building in Belmont. After arriving at the scene on Washington Ave., firefighters managed to bring the flames and smoke under control within the hour, according to the FDNY.

Seven people were transported from the scene to St. Barnabas Hospital with minor injuries, including smoke inhalation, officials said. An eighth victim, a 40-year-old woman, was in critical condition at the same hospital.

The building's first floor houses various businesses, including a grocery store and pharmacy.

The FDNY said the blaze wasn't sparked by an e-bike lithium-ion battery. Fire marshals are still investigating the cause of the fire.
