KYIV—Russia summoned the European Union’s ambassador in Moscow on Tuesday, fuming over what it calls an illegal rail blockade of a Russian outpost on the Baltic Sea, the latest stand-off over sanctions imposed over the war in Ukraine.
On the ground in eastern Ukraine, Russia’s separatist proxies said they were advancing towards Kyiv’s main battlefield bastion. A Ukrainian official described a lull in fighting there as the “calm before the storm.”
