Scores of world leaders are arriving in New York City to speak at this year’s United Nations General Assembly this week. It comes amid rising tensions between the U.S. and North Korea. President Trump is to speak to the General Assembly on Tuesday. On Sunday, Trump called North Korea leader Kim Jong-un “Rocket Man” in a tweet, as the White House continues to threaten military responses to North Korea’s recent missile tests. Trump also claimed that there were long lines at gas stations in North Korea in response to the increasing tightening of sanctions, although multiple news reports dispute the claims. Trump is also planning to have a dinner with the presidents of Peru, Colombia and Brazil at Trump Tower tonight to discuss Venezuela. The Trump administration has threatened to intervene militarily in Venezuela to oust President Nicolás Maduro.
