Ukraine claims 12 cease-fire violations overnight

Despite the reported violations, the level of firing appeared to be far lower than a week ago when a cease-fire was called.

Among the attacks reported by the Ukrainian military was an attempt to storm positions in the village of Shyrokyne near the port city of Mariupol. That city remains of strategic concern to Ukraine because rebel seizure of it could help establish a land corridor between mainland Russia and the Russia-annexed Crimean peninsula.
