Washington Post: US official says Russia likely to seize all of Luhansk Oblast in coming weeks.

The Ukrainian cities of Sievierodonetsk and Lysychansk, which became the epicenter of the battle for Donbas, could fall to Russian forces within a week, the U.S. official quoted by the Washington Post said, speaking on condition of anonymity because of the sensitivity of the issue. This could create a de facto new front line that could last for some time.
