SEOUL — Russian President Vladimir Putin will visit North Korea for talks with leader Kim Jong Un on Tuesday, furthering concerns about the growing military cooperation between the two states at a time when Moscow is hungry for munitions to use in its war against Ukraine.

       The pair will likely use the visit to again pledge public support for each other, rebuffing U.S.-led efforts to isolate Putin over his invasion of Ukraine and Kim over his pursuit of nuclear weapons and ballistic missiles.
