Not a smart move. Where will it go from here? The main island of South Korea? Other Asian islands? Other allied countries?
South Korea had indeed returned fire when the missiles hit the small island.
The casualties include 2 civilians and 2 marines. The bombing injured 18 people and damaged many homes.
After recovering the debris, South Korea studied the artillery and believe that NK used what are called; 'Air-fuel bombs'. These bombs produce a longer lasting blast radius than generic bombs and creates fires which results in more damage and more casualties.
The bombing has resulted in the first civilian casualty since 1987 when North Korea bombed a South Korean air-liner.
The South Korean military is on full alert.
Now that it's started, what will happen next?
The United Nations will step in and try to calm everything down.
The US are pressuring China, "arguing that it has the greatest responsibility when it comes to the stability of the DPRK."
South Korea need to react in a strong and formidable way to show North Korea that they are taking this incident seriously. But they must be careful not to provoke more violence.
"What's so civil about war anyway?"
