The head of a Kremlin-run news agency said President Trump is "more dangerous" than North Korean dictator Kim Jong-un, according to a Monday Bloomberg Politics report.

"Trump is more impulsive and unpredictable than Kim Jong-un," Dmitry Kiselyov said Sunday on his show, "Vesti Nedelyi."

Kiselyov's comment marks a stark contrast from the praise for Trump earlier this year on the same program, which hailed the new president as a chance to warm U.S.-Russian relations.

Kiselyov and other Kremlin mouthpieces also slammed the first family, including Ivanka Trump's role in the White House, according to the news site, saying Kim hasn't given his 4-year-old daughter an official title.

Tension between the two nations has mounted since the U.S. ordered a missile strike on a Syrian airfield after a chemical attack, believed to have been ordered by the administration of Syrian President Bashar Assad, killed dozens of civilians.

Foreign Minister Sergei Lavrov denounced the White House-authorized strike against Assad - whose presidency Russia has backed in Syria's ongoing civil war - earlier this month.

Lavrov additionally urged the U.S. to not take such "a very risky course of action" with North Korea on Monday.

Media outlets controlled by senior Russian officials can hint at the Kremlin's policy shifts.

Dmitry Peskov, also a top Kremlin spokesman, declined Bloomberg's request for comment on whether Kiselyov's statement reflects official Russian policy, saying that his views are "usually close, though not every time."

Bloomberg reported that Kiselyov is known for making extreme statements.

State media outlets have reportedly been building on their anti-Trump message the past several weeks.

A recently released survey conducted by VTsIOM, a state-run pollster, found that a much higher number of Russians now have negative opinion toward Trump: Thirty-nine percent of Russians view him negatively, compared with 7 percent in March.
