The North/South Korean border looks like:
So there are at least 3 (or possibly more) borders that can be crossed:
The North Korea/DMZ border
The military demarcation line
The DMZ/South Korea border
I'm trying to understand what North Korean soldiers do to defectors under relevant international law and treaties. Specifically:
Which border(s) can they actually cross to capture the defector?
Which border(s) can they fire beyond, but not actually personally cross?
What are the repercussions of violating these? Would it be considered an attack on South Korea, or would it be merely a violation of the ceasefire, etc.?
