At least four people were killed and six others injured when a four-storey building collapsed overnight in the Moroccan city of Fez, about 200km (124 miles) east of Rabat, local authorities said on Thursday.
State media 2M had said 11 people were killed before issuing an official correction.
Authorities said a search for others who might still be buried was ongoing.
Local media showed footage of rescuers and residents digging through the rubble.
An investigation has been launched into the incident, and residents of adjacent buildings were asked to evacuate as a precaution against potential further collapses, authorities said.
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.
