PYONGYANG, North Korea—A new North Korean video portrays President Barack Obama and American troops in flames and says the North conducted its recent nuclear test because of U.S. hostility.

The video follows a string of critical rhetoric against the United States. Another video posted earlier this month showed an American city being attacked by missiles.

The most recent video, posted Sunday by a YouTube account affiliated with a pro-reunification government agency, shows a blazing fire superimposed over footage of Obama, and ends with a generic simulation of a nuclear device exploding underground.

The United States currently is negotiating in the Security Council for stronger U.N. sanctions against Pyongyang following a Feb. 12 nuclear test in the far northeast, the country's third since 2006.
