"Despite the truce, the Russian militants fired at Ukrainian electricians who were repairing power line in order to resume electricity supply of Avdiivka. Vice-Premier Hennadii Zubko informed the president. It was impossible to continue repair efforts due to the constant fire.
"The OSCE SMM and international partners of Ukraine were reported about the incident. Ukraine demands Russia to cease the fire immediately," Tseholko wrote.
