WASHINGTON, Feb. 25 - U.S. Secretary of State John Kerry said on Wednesday additional sanctions against Russia are "teed up" should events in eastern Ukraine warrant them, and he suggested a decision may come soon, Reuters reported.

U.S. leaders will look at whether the Minsk ceasefire plan was being implemented or if there was "some other effort that may be taking place which would immediately merit a much more significant response," Kerry told lawmakers.
