More violence has been reported in Eastern Ukraine after two men were pulled from the Donetsk River on Monday.

In eastern Ukraine, the police in Slovyansk pulled two bodies from a fork of the Donetsk River, which loops through the city, the man appointed by militants to serve as the “people’s mayor,” Vyachislav Ponomaryov, told the Russian newspaper Moskovsky Komsomolets.

“Today I went to the morgue to identify another two corpses,” Mr. Ponomaryov said. He said both were pro-Russian militants. They had died, he said, from stab wounds and been thrown in the river. Mr. Ponomaryov said the city was under attack by a Ukrainian nationalist group, Right Sector, and the Ukrainian Army.

Meanwhile Pro-Russian militants captured Ukrainian woman who they say is Irma Krat, an activist who took part in pro-European Union demonstrations last winter. They posted videos of her online with a bag over her head and pleading for help.
