Speaking to reporters during the daily news conference, yesterday the White House Press Secretary Jay Carney said "I would simply say that provocative propaganda is far less concerning to us and to our allies than provocative actions that violate North Korea's commitments to the United Nations and the international community, its flagrant violations of its commitments when it comes to its nuclear weapons program".
The propaganda video showed US President Barack Obama and US troops burning and is followed by a message that North Korea conducted the nuclear test in retaliation to "US hostility".
"We are working with our allies to isolate and pressurise North Korea appropriately, given its continuing defiance of its international obligations," Carney added.
