ISTANBUL (AA) - The death toll in Wednesday's building collapse in Istanbul has risen to 21, Turkey’s Interior Minister said on Saturday.

"Those who are responsible will be held to account," Suleyman Soylu told reporters in Istanbul.

Earlier in the day, Turkey's Health Minister Fahrettin Koca informed that 13 injured people are in hospital, including two in serious condition.

In Istanbul, President Recep Tayyip Erdogan also expressed condolences for the victims of the collapse.

"There are lessons we need to learn," Erdogan said, visiting the building site.

The seven-story building in Istanbul’s Kartal district collapsed Wednesday for reasons as yet unknown, with 30 residents inside.

On Saturday, 9 members of Alemdar family -- who all died during the collapse of the building -- were buried today in a cemetery in Pendik district.
