South Korea's Yoon criticizes North's trash balloons

South Korean President Yoon Suk-yeol has criticized North Korea for "a despicable provocation that would make any normal country ashamed of itself" -- an apparent reference to the North sending balloons carrying trash across the border.

Yoon made the comment in a Memorial Day speech at Seoul National Cemetery on Thursday. The day is dedicated to the war dead, including those who were killed in the Korean War.

Yoon said that "Just around 50 kilometers away from here, our compatriots are suffering from starvation with their freedom and human rights brutally deprived."

He also said, "The North Korean regime refuses to accept the progress of history and instead remains on a backward path, threatening our lives." He added that his government "will never overlook the threat from North Korea."
