U.S. President Donald Trump has issued a new warning to North Korea.

"And if he utters one threat, in the form of an overt threat, which, by the way, he has been uttering for years, and his family has been uttering for years, or if he does anything with respect to Guam, or any place else that's an American territory or an American ally, he will truly regret it and he will regret it fast."

Trump's comments come as the Chinese Global Times says Beijing would not assist North Korea if it launches a first strike that threatens U.S. soil and the U.S. retaliates.

President Trump also said he is considering possible military action against Venezuela in response to President Nicholás Maduro's power grab.

"We have many options for Venezuela, and by the way, I'm not going to rule out a military option. We have many options for Venezuela."

He added that it's "certainly something that we could pursue." Trump had been blasting Maduro's moves to consolidate power, describing him as a "dictator."
