KIEV – Pro-Russian rebels launched an offensive against the strategic port of Mariupol in eastern Ukraine on Saturday, prompting the European Union’s foreign policy chief to warn of a further “grave deterioration” in EU-Russian relations.
Mariupol’s city administration said the rebels had killed at least 30 people and injured 83 others by firing rockets from long-range GRAD missile systems.
The city of 500,000, on the Sea of Azov, is vital for eastern Ukraine’s steel and grain exports and straddles the coastal route from the Russian border to Crimea, the Black Sea peninsula in southern Ukraine seized by Russia last March.
President Petro Poroshenko, pledging to protect Ukrainian territory, said he would convene an emergency meeting of his country’s security council on Sunday. “Today an offensive was launched on Mariupol. This will be the best possible monument to all our dead,” Russia’s RIA news agency quoted rebel leader Alexander Zakharchenko as saying at a memorial ceremony in the separatist-held city of Donetsk.
Zakharchenko said the separatists also planned to encircle Debaltseve, a town northeast of Donetsk, in the next few days, Interfax news agency quoted him as saying.
Eastern Ukraine has seen an escalation of fighting in recent days that Russian President Vladimir Putin has blamed on Kiev. The rebels have ruled out more peace talks.
EU foreign policy chief Federica Mogherini condemned the Mariupol attack and urged Moscow to lean on the rebel leaders. “I … call openly upon Russia to use its considerable influence over separatist leaders and to stop any form of military, political or financial support,” Mogherini said.
In a conversation with Poroshenko, U.S. Vice President Joe Biden condemned “the attacks and violence in eastern Ukraine initiated by Russia-backed separatists,” the White House said.
U.S. Secretary of State John Kerry, on a visit to Zurich, said in a statement that the separatists’ assault has been aided by Russia’s “irresponsible and dangerous decision to resupply them in recent weeks with hundreds of new pieces of advanced weaponry, including rocket systems, heavy artillery, tanks, armored vehicles, in addition to continuing operational command and control.”
Moscow denies sending forces and weapons to east Ukraine, despite what Kiev and the West say is irrefutable proof. Last week Poroshenko said Russia had 9,000 troops stationed in his country and demanded their immediate withdrawal.
