Ukrainian President Petro Poroshenko has agreed to a so-called "Normandy Format" meeting in Berlin on October 19, bringing together Russia, Germany, France and Ukraine for talks on the separatist conflict in eastern Ukraine, a statement said on Tuesday.

Fighting between Ukrainian troops and Russian-backed rebels has killed more than 9,600 since 2014, despite a ceasefire agreed in the Belarussian capital Minsk.

Poroshenko agreed to the talks during a phone call with German Chancellor Angela Merkel and French President Francois Hollande, the statement said.

"The heads of states agreed to have a Normandy Four meeting in Berlin on October 19 in order to put pressure on Russia to fulfill security package of Minsk agreements," it said.
