MELEKHOVO, Russia—Imprisoned Russian opposition leader Alexei Navalny urged his supporters Monday to begin a broad campaign against Moscow’s actions in Ukraine as he went on trial on new charges of extremism that could keep him behind bars for decades.
The trial began inside a maximum security penal colony in Melekhovo, 250 kilometers (150 miles) east of Moscow, where Navalny, 47, is serving a nine-year sentence for fraud and contempt of court—charges he says are politically motivated. Soon after it started, the judge closed the trial despite Navalny’s demand to keep it open.
