Several powerful tornadoes have ripped through the southern US states of Mississippi and Alabama, injuring at least 12 people and damaging or destroying hundreds of homes and businesses, authorities have said.

The city of Hattiesburg in Mississippi's Forrest County bore the brunt of the storms, which hit late on Sunday. The campus of the University of Southern Mississippi was also heavily damaged.
