An explosion destroyed a car near a bridge in central Cairo in Egypt on Monday after a collision, a health ministry spokesman said.
It was not immediately clear what caused the blast. Two security sources told Reuters a faulty battery may have been responsible.
Ministry spokesman Khaled Megahed told journalists three people were injured and transferred to hospital. Another health ministry official told a local radio station that several others were treated for minor injuries.
The security sources said flames from the car spread to a minibus, which Reuters witnesses said was also destroyed, with debris and metal scattered close by.
A civil defence officer told Reuters at the site that at least five people were hurt.
