Russia's foreign ministry said Sunday that a Ukrainian shell hit a Russian border town, killing one person and seriously injuring two others. Ukraine denied firing a shell into Russian territory.
A statement from Russia's foreign ministry labelled the incident a "provocation," and warned of the possibility of "irreversible consequences, the responsibility for which lies on the Ukrainian side."

Russia said the shell hit the courtyard of a residential building in the Russian town of Donetsk — near the Ukrainian city of the same name that has become a rebel stronghold — early on Sunday. Ukraine's restless east has been mired in a pro-Russian separatist insurgency against the Kyiv government.
Ukrainian officials denied that any Ukrainian shells had fallen on Russian territory. Andriy Lysenko, a spokesman for Ukraine's National Security and Defence Council, was quoted by Interfax Ukraine as saying that Ukrainian forces "do not fire on the territory of a neighbouring country. They do not fire on residential areas." He placed blame for the attack on the rebels themselves.
Russia has made repeated claims that settlements along its porous border with Ukraine — which the West and Kyiv say is a key supply route for the rebels — have been hit by Ukrainian fire, but no deaths have been previously reported.
Overnight bombings force evacuations
The claims come as Russian President Vladimir Putin, whose nation will host the 2018 World Cup, is attending Sunday's final in Rio de Janeiro to take part in a handover ceremony with Brazilian President Dilma Rousseff and FIFA President Sepp Blatter.
Brazilian officials said Saturday that both Putin and his Ukrainian counterpart, Petro Poroshenko, would attend the match. But Poroshenko announced Sunday that he wouldn't be going. Talks between Russia and Ukraine over a ceasefire between the rebels and Kyiv's troops have stalled in recent weeks, as Ukrainian troops have succeeded in pushing insurgents out of key towns in the east.
Putin met Sunday with German Chancellor Angela Merkel, also in Rio for the World Cup final, to discuss eastern Ukraine. Merkel spokesman Steffen Seibert said in a statement that the two leaders "agreed that as soon as possible direct talks should take place between the Ukrainian government and separatists in form of a video conference." Selecting a location for talks has been a key sticking point for both sides.
Putin spokesman Dmitry Peskov told Russian news agencies that Putin and Merkel believed the situation in east Ukraine was "deteriorating."
"Putin expressed grave concern with the ongoing attacks from the Ukrainian armed forces, and emphasized that it is unacceptable when such attacks result in the shelling of Russian territory," Peskov said.
Ukraine's Donetsk, where rebels have gathered to regroup after a major Ukrainian offensive last week, was quiet on Sunday. But some 150 people from the settlement of Marynka, on the outskirts of the city, were moving into dormitories at a local university on Sunday, after their homes were bombarded during the night.

"We were brought here this morning," said Svetlana Panteleyeva, who was with her grandson. "We were bombed so terribly.... They blew up our houses."
Artillery fire in Marynka late on Friday left at least four people dead, but the number of casualties in the latest bombing was unclear.
Ukrainian defence officials said Sunday that the air force had performed 16 sorties and carried out five airstrikes on rebel positions over the previous day.
No 'terrorist will evade responsibility'
Interfax-Ukraine cited Lysenko on Sunday as saying that several dozen rebels had been killed and rocket launchers and armoured vehicles destroyed in the attacks. He also said that seven servicemen had been killed and 30 wounded in the past day.
Following the loss of at least 19 soldiers in a rocket attack Friday morning by the pro-Russian militia, Ukrainian officials have claimed to have killed large numbers of rebel combatants, although there has been no independent verification. Late on Friday, Defence Ministry spokesman Vladislav Seleznev said on his Facebook account that 1,000 rebels had been killed in two separate airstrikes.
Poroshenko vowed last week to respond with firmness to attacks by the pro-Russian insurgency.
"For every life of our soldiers, the militants will pay with tens and hundreds of their own," Poroshenko warned Friday. "Not one terrorist will evade responsibility. Everybody will get what is coming to them."
