2Moscow: Fighting between Ukraine government forces and Russian-backed rebels in eastern Ukraine has escalated sharply in recent days, with each side blaming the other for the violence.
3At least nine people were killed in artillery strikes in villages and towns on both sides of a ceasefire line on Monday.
4US officials have said that one three-day period of fighting along the front last week was the most intense since a February ceasefire.
5Neither side has openly renounced the ceasefire, but European monitors of the accord say both have been pulling heavy weapons out of storage sites and putting them to use.

7The US State Department blamed Russia and pro-Russian rebels for the rise in violence.
8American officials have characterised the fighting as possibly a new attempt by Russia to destabilise the Ukrainian government.
9"Russia and the separatists are launching these attacks, just as they escalated the conflict last August," the department's spokesman, John Kirby, told reporters in Washington.
10"Efforts by Russia and separatists to grab more territory will be met with further costs."
11Russian President Vladimir Putin on Tuesday blamed Ukraine.
12After emerging from a dive in a miniature submarine in the Black Sea off the coast of Crimea, the peninsula Russia annexed last year, Mr Putin said that, "regrettably, we are now seeing this conflict escalation and the blame lies not with the Donbass militia but with the rival side".

14Russian Foreign Minister Sergei Lavrov said on Monday that the Ukrainian authorities had failed to carry out the political points of the February ceasefire, which he said called for Kiev to cede power to the two separatist regions.
15The Ukrainians, he said, are "more concerned over how to keep alive Russophobia in the West and how to artificially whip up tension".
16Before the latest escalation, four vehicles belonging to the Organisation for Security and Co-operation in Europe were burned outside the Park Inn hotel in Donetsk, limiting the group's ability to monitor rebel military actions.

18Ivica , the foreign minister of Serbia, which holds the chairmanship of the OSCE, issued a statement last week condemning the arsons and subsequent resumption of fighting, at the time focused around one village, Starohnativka, north-east of the strategic Ukrainian-controlled port of Mariupol.
19Since then, skirmishes have become general along the length of the front, the European monitoring mission's statements suggest.
20On Saturday, European monitors reported hearing 184 explosions in Donetsk that were consistent with mortar fire on the front that runs through the city's outlying north-western districts.
21South of Donetsk, along a river that roughly defines the front line, monitors found fresh craters from howitzers and rocket artillery on both sides.

23On the government side, monitors noted that the Ukrainian army had removed eight Grad rocket-launching trucks from a holding area, where they had been taken to comply with the ceasefire.
24The separatist news agency DAN reported that artillery fire killed three people in the town of Horlivka and two in Donetsk.
25The Ukrainian army reported that one soldier was killed in the fighting, and officials said that two people were killed overnight Monday from shelling in a Ukrainian-held village on the outskirts of Mariupol.
26A third resident of the village, a mother who had been caught in the open with her 10-year-old daughter while running for cover, died on Tuesday in a hospital.

28The violence prompted the leaders of France, Germany and Ukraine to arrange to meet again in Berlin on Monday, French Foreign Minister Laurent Fabius said.
29Ukraine is preparing to mark its Independence Day next week.
30More than 6500 people have been killed in the conflict since it erupted in April 2014 after Russia annexed Ukraine's Crimea Peninsula in reaction to the fall of a Moscow-backed president to mass protests in Kiev.

32"Its worrying," Mr Fabius told reporters ahead of the meeting between his president, Francois Hollande, Ukrainian President Petro Poroshenko and German Chancellor Angela Merkel.
33"Military operations must stop and arms be withdrawn | Secondly, we need to right conditions for elections in the Donbass [eastern Ukraine]," he said.
34"I hope Monday's meeting will allow us to advance on both points. We hope to have a solution by December at the latest."
