More people than initially thought remain trapped beneath a collapsed four-storey department store in a suburb of Ghana’s capital Accra that killed at least seven people the previous day, officials said on Thursday.The authorities had initially estimated that around 55 people were inside when it collapsed due to a suspected structural failure, but that figure was based on the number of employees working there at the time and did not factor in the number of shoppers too.By Thursday morning, emergency personnel had pulled out 61 survivors and recovered seven dead bodies from the building, which housed a mall operated by Indian retailer Melcom Ltd.A team of Israeli experts was due to arrive in the West African nation on Thursday to assist a search for remaining survivors as rescue workers said they feared their condition was quickly deteriorating."It is now clear that more people were in the shop than initially estimated, and it is difficult to tell the actual numbers at this moment,” Kofi Portuphy, the head of Ghana’s National Disaster Management Organisation, told Reuters.
