Russia must provide the OSCE Special Monitoring Mission (SMM) unfettered access to Donbas, eastern Ukraine.

"An OSCE SMM drone that spotted an illegal convoy from Russia was jammed and then lost in Russia-controlled eastern Ukraine. Russia must provide the OSCE's SMM unfettered access to eastern Ukraine, and implement all Minsk agreement provisions," Spokesperson for the U.S. Department of State Heather Nauert said in a statement on October 30.

As UNIAN reported earlier, the OSCE Special Monitoring Mission to Ukraine on October 27 lost its long-range unmanned aerial vehicle (UAV), which was monitoring the movement of a convoy of trucks in the Russian-occupied area in the east of Ukraine.

"For about 35 minutes before communications were lost, the UAV had experienced signal interference, assessed as jamming, at intervals in areas near Saurivka and Nyzhnokrynske. The UAV did not return to its ground control station near Stepanivka (government-controlled, 54km north of Donetsk) and is considered lost," it said.
