Bulldozers continued to excavate rubble on Friday night, at the site of a fireworks factory explosion in Hendek, which took place earlier in the day, killing four and injuring nearly 100.
Reports estimate that at least 45 factory workers are still unaccounted for.
According to Turkish President Recep Tayyip Erdogan, 189 workers were in the facility at the time of the explosion, which took place at around 11:15 local time (08:15 GMT). The president added that the fire was under control.
An investigation is underway to determine the cause of the incident.
