(QHA) -

Kazakh President Nursultan Nazarbayev and Ukrainian counterpart Petro Poroshenko agreed Thursday that the delayed talks on the Ukraine conflict with leaders of Russia, France and Germany will take place at the end of the month, Kazakhstan said Thursday.

In a telephone call, the two leaders "noted that the meeting of leaders of Ukraine, Russia, Germany and France in Kazakhstan's capital Astana will happen at the end of January," the Kazakh presidency said in a statement.

President Vladimir Putin's spokesman, Dmitry Peskov, was quoted as saying the date of a summit could be announced only when plans were finalized.

But German Chancellor Angela Merkel and French President Francois Hollande said they would only attend if progress was made on the implementation of a cease-fire and peace plan for eastern Ukraine, and the meeting did not materialize.

At least 12 civilians were killed when a rocket hit a bus on January 13, one of the deadliest incidents since the cease-fire deal was signed on September 5.
