UN headquarters also features the famous Hall or Flags or the huge General Assembly Hall, where South Korean boy band BTS performed last year, and a first-rate art collection.

US Secretary of State Marco Rubio said Monday that this week is “very critical” for Donald Trump’s plan to end the war in Ukraine. Russia’s Vladimir Putin made news on Monday by offering a three-day ceasefire beginning on May 8, a move perhaps motivated by skeptical recent comments from Trump on Russia’s willingness to bargain in good faith.
