Russia, Ukraine continue air attacks

MOSCOW/KYIV — Russia and Ukraine continued aerial attacks on each other, officials said on Sunday, as the fate of a proposed ceasefire to the three-year-old conflict remained uncertain.

Russian President Vladimir Putin said on Thursday he supported in principle Washington's proposal for a 30-day cease-fire with Ukraine but that his forces would fight on until several crucial conditions were worked out.

Both sides have since traded heavy aerial strikes, and Russia moved closer on the battlefield to ejecting Ukrainian forces from their months-old foothold in the western Russian region of Kursk.
