Ghanaian officials say faulty construction is to blame for the deadly collapse of a multi-story shopping center in the capital, Accra.

The building collapsed early Wednesday, killing at least seven people. Authorities say more than 60 survivors have been pulled from the rubble.

Rescue efforts are continuing, and an 18-person team from Israel is expected to arrive Thursday to help search for remaining survivors.

Ghana's President John Dramani Mahama has vowed to hold responsible whoever is at fault for the collapse.

A statement from Mr. Mahama's office Thursday said the collapse exposed faults in the country's building codes. The president said other high-rise buildings must be inspected to see if more disasters are close to happening.

The mall is run by Melcom, an Indian-owned company. Melcom chief operation officer Arvinder Singh has denied responsibility for the collapse, saying the company only rented the building.
