The pen may be mightier than the sword, but a fax from North Korea is mightier than both.
North Korea allegedly sent a fax to South Korea Thursday afternoon, threatening to "strike mercilessly without notice," CNN reports.
The South Korean News agency Yonhap reported the fax came as a response to anti-North protests that erupted in South Korea's capital of Seoul. The rallies and protests were held on the second anniversary of former North Korean leader Kim Jong Il's death.
The fax was purportedly sent by the North Korean Military who saw the rallies as an insult to the "highest dignity," NBC News reports.
The fax cited the "extra-large provocations" occurring in the streets of Seoul and warned of retaliation for the disrespect being shown to its former leader.
The South retaliated with a fax of their own that guaranteed "resolute punishment" for any offenses made, Fox News reported.
"We warned that if North Korea is to carry out provocation, we will firmly retaliate," Kim Min-seok, spokesman for South Korea's Ministry of National Defense said in press statement.
CNN reports that threats from North Korea to South Korea are fairly standard as relations between the contentious nations teeter between inhospitable and downright hostile.
Some are hoping that "basketball diplomacy" might improve relations as former NBA star Dennis Rodman visits North Korea to hold tryouts for an exhibition basketball game that will take place next month. Rodman has become good friends with North Korea's leader Kim Jong Un but says he has no intention of playing diplomat for the U.S. or any other nation.
"I understand what's going on with the political stuff, and I say, I don't go into that venture, I'm just doing one thing for these kids here, and for this country, and for my country, and for the world pretty much," he told NBC News.
