Cease-fire deal offers 'only hope of peace'

A cease-fire deal brokered by Europe remains the only way to secure peace in Ukraine, the European Union's foreign policy chief Federica Mogherini said on Tuesday.

"We have to make it succeed. This is the only agreement that was signed by the parties, it has been supported by a UN Security Council resolution, and it is the only way we have to make peace possible in Ukraine," Mogherini told BBC radio during a trip to London.

Fighting between the Ukrainian military and militias, which has killed more than 5,600 people, has continued despite a weeklong truce, putting the deal under pressure of collapsing.
