The truce in Ukraine may be facing the most serious test in more than three months as the government in Kiev said pro-Russian rebels were staging a large-scale offensive.

The army repelled an attack on the Donetsk-region town of Maryinka by separatists who then switched their focus to other nearby locations, spokesman Yevhen Sylkin said on Channel 5. The rebels said they were halting an assault by the army. The ruble extended losses, though Ukrainian assets advanced.
