UPDATE:

Ukraine has now retracted its earlier statement about a cease-fire agreement. A spokesman now says the earlier announcement was too optimistic and didn’t accurately characterize the conversation between Ukraine and Russia. From the New York Times:

The office of President Petro O. Poroshenko of Ukraine said Wednesday that he and President Vladimir V. Putin of Russia had a similar understanding about what was needed to achieve a cease-fire in southeastern Ukraine, but it retracted a statement it had made earlier in the day that said the two men had agreed to a “lasting cease-fire.”

The initial statement, posted on the presidential website, went too far in describing the results of a telephone call between the two leaders as having reached a cease-fire, said a spokesman, noting that a revised version would be posted shortly.

The presidents exchanged opinions about a cease-fire, but there was no formal agreement, said the spokesman, who, in line with protocol, did not give his name.

Ukraine’s president turned to Twitter early Wednesday morning to announce that a cease-fire agreement with Russia had been reached.

According to a statement from Ukrainian President Petro Poroshenko’s office, the agreement came after a telephone conversation with Russian President Vladimir Putin.

“The result of this conversation was the agreement on a permanent cease-fire in the Donbass,” the statement said. “There was a mutual understanding on steps that promote peace.”

Immediate details were not available.

Ukraine recently accused Russia of sending troops and weaponry into Eastern Ukraine, calling it a slow-motion invasion.

Over the weekend, the European Union leaders agreed to prepare a new round of sanctions that could be enacted in a week, after NATO accused Russia of sending tanks and troops into southeastern Ukraine. A NATO summit in Wales on Thursday is also expected to approve measures designed to counter Russia’s aggressive actions in Ukraine.

U.S. President Barack Obama arrived in Estonia Wednesday morning in a show of solidarity with NATO allies who fear they could be the next target of Russia’s aggression.
