More from our news desk on the failed talks:
Peace talks in Minsk aimed at ending the fighting in eastern Ukraine ended without progress on January 31.
Ukraine's representative at the talks, former President Leonid Kuchma, told Interfax that the two separatist representatives at the talks issued ultimatums and refused to discuss a plan "for a quick cease-fire and a pullback of heavy weapons."
The more than four hours of talks, held at the Belarusian Foreign Ministry building, included Russian Ambassador to Ukraine Mikhail Zurabov, Organization for Security and Cooperation in Europe representative Heidi Tagliavini, and rebel representatives Denis Pushilin and Vladislav Deinego.
Pushilin, for his part, said the separatists will reject ultimatums and accused Ukraine of blocking the peace process.
Kuchma also criticized the two main self-proclaimed separatist leaders in eastern Ukraine -- Aleksandr Zakharchenko and Igor Plotnitsky -- for not attending the talks as signatories of the original Minsk agreements signed in September.
Barring any major developments, that ends the live blogging for today.
