Russian President Vladimir Putin made a surprise visit to occupied Mariupol, the Kremlin said early Sunday. His trip to the Ukrainian city, which was devastated last year in a deadly Russian siege and is about 60 miles from the battlefront, is a show of defiance following the arrest warrant that the International Criminal Court (ICC) issued for him over alleged war crimes in Ukraine. It was Putin’s second foray into occupied Ukraine this weekend, following a visit to the Crimean peninsula.
