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.
