A technical malfunction involving cable or transformer explosions caused significant disruptions on the M5 Üsküdar-Sultanbeyli metro line in Istanbul at the Ihlamurkuyu Station. The incident resulted in heavy smoke in the tunnels and required the evacuation of passengers, some of whom reportedly waited in the tunnels for approximately 45 minutes.

Metro Istanbul confirmed that services were limited to running between the Üsküdar-Çakmak and İmam Hatip Lisesi-Sultanbeyli stations following the fault.
