All the major details of the build-up of pro-Russian separatist uprising around Eastern Ukraine.
Petro Poroshenko, the newly elected Ukrainian president, says fighting in the separatist east of the ex-Soviet country must stop by the end of the week.
“We must end the fighting this week. For me, every day in which people die, every day in which Ukraine pays such a high price, is unacceptable,” Poroshenko said in a statement published on his official website on Sunday.
“And to do that, we must restore the Ukrainian border so that the safety of each Ukrainian citizen is guaranteed.”
His comments followed a round of talks with Moscow’s ambassador to Kiev and an envoy from the Vienna-based Organisation for Security and Cooperation in Europe (OSCE), and came a day after the 48-year-old confectionery tycoon was sworn into office as the fifth post-Soviet president of Ukraine.
Both fighters and weapons have been crossing into Ukraine’s industrial rustbelt from Russia since shortly after the conflict began eight weeks ago.
Russian President Vladimir Putin issued orders on Saturday for security at the mutual border to be stepped up – a move demanded by both US President Barack Obama and several European heads of state.
In a separate development, Ukraine, Russia and European Commission officials will meet in Brussels on Monday evening to continue talks on how to resolve a dispute over gas prices.
The trilateral meeting, initiated by the Commission, is scheduled to start at 1700 GMT, with European Union Energy Commissioner Guenther Oettinger, Russian Energy Minister Alexander Novak and Ukrainian Energy Minister Yuri Prodan in attendance.
