Russian Foreign Ministry spokesperson Maria Zakharova accused Ukraine on Thursday of carrying out over 30 attacks on energy infrastructure since a US-mediated moratorium was put in place last month.
"The attacks on Russia's energy infrastructure are targeted and are purely provocative and demonstrative," Zakharova told reporters.
Zakharova said Ukraine had used Western-supplied weapons to target both Russian territory and Russian-controlled areas in Ukraine, adding that Moscow reserved the right to withdraw from the ceasefire if violations continued.
