The official statement was published on the German governmental website, Censor.NET reports citing Reuters.
Merkel and Macron said they were concerned that the security situation in eastern Ukraine had not significantly improved since they held a four-way telephone call with Russian President Vladimir Putin and his Ukrainian counterpart Petro Poroshenko in the so-called Normandy format on Aug. 22.
"We urge President Putin and President Poroshenko to fully respect their commitments, to support the cease-fire in a public and clear manner, and to ensure that appropriate instructions have been sent to the military and local forces," they said in a joint statement issued by the chancellery in Berlin.
They said the cease-fire agreement was still violated too often, including with the use of heavy weapons. They called on all parties to provide observers from the OSCE security watchdog with safe and unimpeded access to areas within the battle zones.
"The OSCE observer mission continues to report threats to its staff and restrictions on their freedom of movement, particularly in the areas not controlled by the Ukrainian government," Merkel and Macron said.
Both the European Union and the United States imposed broad economic sanctions on Russia's financial, defense and energy sectors in response to Moscow's annexation of Crimea from Ukraine in 2014 and its direct support for separatists in eastern Ukraine.
