Minister Suleyman Soylu spoke late Saturday, saying those who made “mistakes” would be held accountable. The eight-storey building in the city’s Kartal district collapsed on Wednesday

Rescue workers remain at the site, and it is unclear how many more people are missing. The collapsed building had 14 apartments, 43 registered residents and three businesses

Thirteen people pulled from the rubble have been hospitalised, and seven remain in intensive care. Chief Doctor Recep Demirhan says that two are in very serious condition, according to Turkey’s official Anadolu news agency

Officials have said the top two floors of the building were built illegally using low-quality construction materials
