A meeting of foreign ministers of Russia, Ukraine, France and Germany intended to shore up a shaky peace process in eastern Ukraine has ended without visible progress.

Russian Foreign Minister Sergey Lavrov told reporters after Tuesday's talks that "there were no breakthroughs," adding that disagreements on security and other issues remain.

The ministers' talks follow last month's meeting of the four nations' leaders, who agreed to work out a "road map" on implementing the February 2015 Minsk agreement sponsored by France and Germany. The deal has helped reduce fighting between Ukrainian troops and pro-Russia separatists, but clashes have continued and political settlement has stalled.

Russia and Ukraine have blamed each other for the lack of progress in settling the conflict that has killed more than 9,600 since April 2014.
