South Korean activists have launched tens of thousands of anti-Pyongyang gas-filled balloons into North Korea on Monday for the second time in three days, amid growing military tensions on the peninsula.
The conservative activists, including many North Korean defectors, launched 100,000 gas-filled balloon criticising North Korean leader Kim Jong-Un over the heavily militarised border.
Some of the slogans on the balloons read: “Launch merciless blow of fire to the nuclear maniac Kim Jong-Un!” or “We want Kim Jong-Un’s head!”
On Saturday the same group, called Fighters for Free North Korea, launched 50,000 leaflets to commemorate the anniversary of the sinking South Korean warship in 2010.
South Korea blamed a North Korea for the submarine sinking, however, Pyongyang has denied involvement and did not claim any responsibility.
"We plan to launch 10 million leaflets over the next three months, condemning the North's latest atomic test and urging the North to abandon the nuclear programme," the group said on its website.
The balloon protest has long angered Pyongyang, which has threatened military retaliation against the activist group.
North Korean frontier guards attempted to shoot down a set of balloons in October 2014, causing a brief exchange of fire across the border.
Since South Korea began annual joint army exercises with the United States this month, tensions on the divided peninsula have been particularly high.
The North has issued a series of threats in recent weeks, including warnings of nuclear attacks against Seoul and Washington.
