A six-storey shopping mall collapsed in the Ghanaian capital Accra on Wednesday and an unknown number of victims were feared trapped in the rubble, witnesses and an AFP correspondent said.

"I was very close to the mall because I was going to buy something only for me to see the building coming down," witness Ama Okyere told AFP. "I had to run for my life. I was so terrified. I believe there are lots of people trapped under this because this is a heavily patronised shopping mall in the area."
