In a stunning Oval Office remark, U.S. President Donald Trump compared the Russia-Ukraine war to “two kids fighting,” saying it might be better to let them brawl before stepping in.

At least 40 people were injured in Kharkiv, including a newborn baby and a 14-year-old girl, officials said, as Russia continued its deadly retaliatory strikes on Ukraine this week.

President Trump opened his remarks at the Group of 7 gathering of industrialized nations by criticizing the decision to expel Russia from the bloc after Moscow’s 2014 “annexation” of Crimea.
