BRUSSELS (AP) -- European Union President Donald Tusk says the test of Thursday's Minsk agreement will be whether a weekend deadline for a cease-fire in eastern Ukraine holds.
Tusk called the agreement, brokered by German Chancellor Angela Merkel and French President Francois Hollande, "welcome news and gives hope" but added that "hope is not enough."
Tusk said "the real test is the respect of the cease-fire on the ground."
Under the deal, Ukraine will trade broad autonomy for the east for control of the Russian border by the end of the year and a cease-fire should kick in on midnight Saturday. Tusk said ahead of an EU summit of government leaders that "we have to be cautious."
