Russia heads into the third month of its invasion of Ukraine on Sunday with no end in sight to fighting that has killed thousands, uprooted millions and reduced cities to rubble.

In the face of mounting sanctions and fierce Ukrainian resistance bolstered by Western arms, Russia has kept up its long-distance bombardment and opened up a new offensive in the east.
