Protesters vow to indefinitely block rail lines to east:
Ukrainian nationalists have vowed to indefinitely block a railway line into eastern Ukraine to protest against trade with Russia-backed separatists.
Volodymyr Parasyuk, a deputy of the Verkhovna Rada, told Ukraina 112 TV on January 27 that "all the railways will be blocked" and "the action will last more than just one or two days -- it will be indefinite."
The blockade aims to stop both legal and illegal contraband trade with areas controlled by separatists and is being carried out by members of parliament and several dozen former volunteer fighters for the government.
The blockade has held up 12 freight trains with more than 700 coaches since it began on January 26, TASS reported.
Kyiv in 2015 banned almost all trade with separatist strongholds, prompting a boom in smuggling. The only commodity that can be obtained legally from the region is coal.
The pro-Kyiv governor of the Lugansk region, Yuriy Harbuz, warned that the blockade "threatens the energy security of the country," in the height of winter.
Harbuz said the protesters "had blocked empty train cars intended to transport coal into the territory controlled by Ukraine."
"If fuel supplies aren't restarted, heat and power stations in central and western Ukraine will be left without fuel," he warned. (AFP, TASS, RFE/RL's Ukrainian Service)

Former Separatist Leader From Luhansk Reportedly Dies In Russia
Russian media reports say a former leader of Russia-backed separatists in Ukraine's Luhansk region has died in Russia at the age of 46.
Reports say Valeriy Bolotov, a Luhansk businessman who acted as a separatist leader in the region in 2014, was found dead in his apartment in Russia on January 27.
There were conflicting reports about whether his apartment was in Moscow or outside the Russian capital.
There was no immediate confirmation of the cause of Bolotov's death, though Russian state media quoted sources as saying he died of a heart attack.
Several prominent separatists have died or been killed in murky circumstances, while others have survived assassination attempts.
Bolotov himself survived an attempted assassination during his time as a self-declared leader in Luhansk.
Infighting among the Russia-backed separatists has repeatedly bubbled into public view since their war against the Kyiv government's forces broke out in April 2014.
Despite significant evidence of Russia's involvement in eastern Ukraine, Moscow denies supporting the separatists with troops and weaponry.
