North Korea has opened a YouTube account sharing clips praising the isolated communist state and denying allegations that it sank a South Korean warship.
Eleven clips under the name of uriminzokkiri, a North Korean government website, appeared today.
One English-language video almost six minutes in duration praises leader Kim Jong-Il, calling him a 'general sent by the heaven'.
Another clip posted a week ago berates South Korean Foreign Minister Yu Myung-Hwan over his controversial remarks that young South Korean leftists should not enjoy freedom in the South but should live under Kim Jong-Il.
A third clip ridicules Seoul for its failure to prevent the UN Security Council from including Pyongyang's denial in its statement deploring the deadly March sinking of the Cheonan warship.
The North denies responsibility for the sinking of the Cheonan near the disputed inter-Korean sea border in the Yellow Sea, which claimed 46 lives.
Tensions have risen sharply since late May when South Korea and the US, citing a multinational investigation, accused the North of torpedoing the corvette, the Cheonan.
North Korea has been expanding the use of the internet in its propaganda offensive, Yonhap news agency said.
In June, a North Korean woman uploaded a clip praising the communist state on YouTube, drawing media attention in South Korea and abroad.
