"North Korea Escalates Trash Balloon Campaign Against South Korea"

North Korea has launched hundreds of trash-carrying balloons into South Korea as retaliation for anti-North Korean leaflets sent by activists. The balloons, which contained waste but no dangerous substances, have heightened tensions between the two countries. South Korea's military is recovering the debris and has advised the public to report any suspicious objects. North Korea's actions follow a series of provocative steps, including missile launches and a failed spy satellite attempt.
