U.S. Secretary of State John Kerry called the release of seven European military observers Ukraine a positive step, but said more is needed to ease tensions.
Mr. Kerry said it’s important that Russia withdraw support for separatists, who have seized government buildings in about a dozen cities and towns in Ukraine.
Mr. Kerry, who is in Africa, spoke by telephone with Russian Foreign Minister Sergey Lavrov on Saturday.
Mr. Kerry said they discussed the violence in Odessa, where at least 42 people died in clashes between government supporters and opponents on Friday, and that everything possible must be done to end it.
