From RFE/RL's News Desk:
A third person has died as a result of a bombing in the eastern Ukrainian city of Kharkiv.
The Kharkiv city council's press service said on February 23 that a 15-year-old boy has also died from the injuries he received in the blast.
Two people -- a policeman and an activist -- were killed by the bombing on February 22, which occurred during a march in Kharkiv marking the Maidan antigovernment protests in Kyiv one year ago that ousted President Viktor Yanukovych.
Those events in Kyiv helped spark the conflict that is currently raging in eastern Ukraine.
Meanwhile, parliament member Dmytro Tymchuk said Russian-backed separatist forces are concentrating near the southern Ukrainian port city of Mariupol.
Tymchuk posted a message on his Facebook page on February 23 saying that some 350 additional rebel fighters and about 20 armored vehicles -- including six tanks -- had arrived since February 22 to reinforce separatist units in the nearby Bezimenne district.
