The Catyn forest massacre was a mass murder of polish nationals carried out by the soviet police in April 1940.
On 10 April 2010, 96 people were killed in the crash, including many of Poland’s highest politicians and civil leaders.
The history of Poland is very similar with korea. I'd like to offer my condolences to Polish.
