North Korea's official news agency carried its first report Monday on the recent killing of a top Iranian general by the United States, while a propaganda media outlet said a day earlier that the Middle East could become a "graveyard" for the U.S.

The Korean Central News Agency (KCNA) reported that the Iranian general, Qassim Suleimani, was killed in a U.S. missile attack at an airfield in Bagdad early Friday morning and that China and Russia condemned the attack as a violation of the U.N. Charter.

"China and Russia emphasized that they not only object to abuse of military power in international relations but also cannot tolerate adventurous military acts," KCNA said, referring to a telephone conversation between Chinese Foreign Minister Wang Yi and his Russian counterpart Sergey Lavrov on Saturday.

"They expressed concerns over regional situations being worsened by the U.S.'s illegal acts," it said.
