One of the power rails in the tower’s elevators was hit by a short circuit, broadcaster BFMTV said, citing sources from the tower operator company SETE.
The technical problem took place between the second floor and the tower’s peak, setting off a fire alarm at 10.50 am (0950GMT), according to Anadolu news agency.
SETE evacuated the building “in line with security procedures,” and no visitors were in danger, BFMTV reported.
Firefighters and technical maintenance units of the tower are looking into the cause of the short circuit, and the tower is expected to “gradually” open to visitors through the second floor later in the day, the broadcaster added.
