Ukraine's oil depot blast seen as preparation for counter-offensive.

A Ukrainian military spokesperson said that undermining Russia's logistics is part of the preparation for the expected Ukrainian counter-offensive, after a fire destroyed a large Russian fuel depot in Crimea. While not directly admitting to striking the fuel storage facility, Ukraine's military command said that "a fire" destroyed 10 oil tanks with a capacity of about 40,000 tonnes. Ukraine said it was wrapping up preparations for the counter-offensive against Russian forces, although officials gave no date for when that would happen.
