Ukraine's President says he has decided to lift a ceasefire because "terrorist" pro-Russian separatists had violated the agreement.
"We will attack and free our lands. The decision not to continue the ceasefire is our answer to terrorists, militants and marauders," Petro Poroshenko said.
The Ukrainian authorities said 27 of their military personnel had been killed since the beginning of the ceasefire on June 20th.
