Fez, a former capital dating back to the eighth century and the country's third-most-populous city, has seen similar incidents in recent months, including one in December when two buildings collapsed, killing at least 22 people.

In 2010, the collapse of a minaret in the historic northern city of Meknes killed 41 people.

Adib Ben Ibrahim, housing secretary of state, said last year that approximately 38,800 buildings across the country had been classified as being at risk of collapse.
