KIEV, Sept. 8 - Ukraine still faces the threat of a full-scale Russian military attack despite several days of relative calm on the front-lines of the east where government forces confront Russian-backed separatists, President Petro Poroshenko said on Tuesday, Reuters reported.

Poroshenko comments at a government meeting come amid signs of discord in the governing coalition over his peace efforts and disenchantment over falling living standards and economic hardship.
