Help began pouring into one of the poorest regions of the US after a deadly tornado wrought a path of destruction in the Mississippi Delta, even as new storms struck Georgia, where two tigers briefly escaped their badly damaged safari park.

At least 25 people were killed and dozens of others were injured in Mississippi as the storm ripped through several towns along its hour-long path late on Friday. One man was killed in Alabama after his trailer home flipped over several times.
