South Korean activists have floated giant balloons carrying boxes of socks into North Korea.
The activists hoped Saturday that North Koreans could wear the socks or trade them for food during the harsh winter. Associated Press video showed five helium-filled balloons rising into the air at an observation post in the South Korean border city of Paju.
South Korean activists have used balloons in the past to send anti-North Korean leaflets across the heavily guarded border.
North Korea strongly denounces the leaflets but hasn't mentioned past efforts to send daily necessities.
