Ukraine and Russia attacked targets on each other's territory on Thursday after brief direct talks between the two sides failed to make any progress on steps to end nearly three-and-a-half years of war.

Fox News senior strategic analyst Gen. Jack Keane (ret.) joins ‘America’s Newsroom’ to break down the prisoner swap between Russia and Ukraine, and what it signals for future ceasefire negotiations.
