Slasher Attacks U.S. Envoy

U.S. ambassador to Korea Mark Lippert was injured in a slasher attack on Thursday morning. Lippert was about to give a speech at a meeting in Seoul.

A man reportedly slashed the envoy's face and wrist with a knife, shouting "The two Koreas must be reunified."

Lippert has been taken to hospital but his injuries are not life-threatening.

The 56-year-old attacker was arrested at the scene and is being questioned by police.
