At least two people were killed Tuesday when a masked gunman opened fire at a mall in the western US state of Oregon, sparking panic before apparently turning the gun on himself, police said. At least one person was also injured in Clackamas, south of Portland, a sheriff's spokesman said, after local media reported a gunman wearing body armour opened fire with a semiautomatic rifle near a Macy's department store.

The gunman was wearing a kind of hockey mask and shouted "I am the shooter" as he moved through the mall, KGW television cited witnesses as saying.
