KYIV (Reuters) -Ukraine has chalked up a string of victories more than a week since blindsiding Russia with a lightning cross-border assault, but the risks are piling up as its troops make plans to hold territory and Russia recovers its footing.
Ukraine poured thousands of troops into the western Russian region of Kursk last week, pulling down Russian flags in towns seized by its soldiers and wresting the war initiative from Moscow for the first time in months.
