A Ukrainian soldier inside the Belbek military base gets an affectionate pet from a woman who was among approximately two dozen who spent the night outside the gate in support of the men on March 3, 2014 in Lubimovka, Ukraine. Tensions at the base, where between 300 and 400 Ukrainian soldiers are stationed, were high overnight as a 4pm deadline the day before reportedly given by Russian troops for the Ukrainians to surrender passed and the troops feared the Russians might attack the base overnight. Many of the soldiers have family that live in apartment blocks just outside the base and about two dozen family members braved the cold ready to block the road to the base entrance should the Russians appear.
