FRANKFURT — German Chancellor Angela Merkel and French President Emmanuel Macron are urging both sides in eastern Ukraine to live up to cease-fire agreements amid a recent upswing in clashes between Russia-backed separatists and Ukrainian forces.



The statement comes a day after US officials said they would begin sending lethal weapons, including anti-tank missiles, to equip Ukrainian troops.



Merkel and Macron issued a joint statement yesterday urging combatants to observe the Minsk agreements aimed at defusing the conflict. Those provisions include the withdrawal of heavy weapons such as tanks and rocket launchers from the front-line area and an exchange of prisoners.



The two leaders also urged the return of Russian military officers to a joint coordination center that plays a role in monitoring the cease-fire. Russian President Vladimir Putin and Merkel discussed the issue Thursday. Putin said the Russian move had been prompted by "restrictions and provocations" by Ukrainian authorities that made it hard for Russian officers to perform their duties.



Merkel and Macron said in their statement that "there is no alternative to an exclusively peaceful solution to the conflict."



Fighting between Ukrainian troops and Russia-backed separatists has killed more than 10,000 people since April 2014.



Merkel and Macron did not comment in their statement on the US decision to supply weapons to Ukraine.
