Censor.NET reports quoting Acting Department Spokesperson Mark Toner.
"The United States again calls upon Russia to use its influence with the separatists to take the first step toward peace to eastern Ukraine and ensure a visible, verifiable, and irreversible improvement in the security situation," Toner said in a statement following the death of an OSCE mission monitor in the Donbas on April 23.
"This incident makes clear the need for all sides - and particularly the Russian-led separatist forces - to implement their commitments under the Minsk agreements immediately," the document notes. "This includes a real and durable ceasefire, withdrawal of heavy weapons, and disengagement from the line of contact."
"The brave monitors of the SMM have the full support of the United States, and we condemn in the strongest terms all acts of hostility and intimidation toward SMM monitors," Toner noted.
He reiterated that the OSCE mission personnel "must also have safe, full, and unfettered access throughout the conflict zone."
As reported, a United States national was killed in OSCE SUV blast April 23 near the village of Pryshyb in the militants-held territory of Ukraine's eastern Luhansk region. Two more monitors, nationals of Germany and the Czech Republic, were injured.
