The OSCE Special Monitoring Mission to Ukraine (SMM) published a report based on information received as of 19:30, 17 February 2019. The SMM saw an aircraft flying over non-government-controlled areas in the security zone. It assessed it as a swept wing four-engine turbo-prop aircraft, likely a Tupolev TU-95 or Tupolev TU-142. This was reported on the OSCE website.
"At 10:00 on 15 February, while positioned in the south-western outskirts of Starobesheve (non-government-controlled, 32km south-east of Donetsk), the SMM saw a flying object south-east of its location flying from south-west to north-east. Based on hand-held imagery, the SMM assessed it as a swept wing four-engine turbo-prop aircraft (likely a Tupolev TU-95 or Tupolev TU-142). From 10:50-11:10, positioned in an area north-west of Liubivka (formerly Leninske, non-government-controlled, 43km south-east of Donetsk), the SMM saw an aircraft (likely a Tupolev TU-95 or Tupolev TU-142) east of its location flying from north to south and back again," the message says.
The report states that the Mission saw weapons in violation of withdrawal lines in government-controlled areas of the Luhansk region. The Mission recorded ceasefire violations inside and near the Zolote disengagement area, and military hardware and personnel inside the Petrivske disengagement area.
As it was reported earlier, on February 18, militants went on the offensive and attacked Ukrainian strongholds near the Zolote settlement in Donbas. As journalist Yurii Butusov reported the battle began around 5:00 a.m., the occupants are applying all weapons, including 152-mm artillery and 120-mm mortars. One Ukrainian serviceman was killed and four were severely wounded.
President of Ukraine Volodymyr Zelensky called the February 18 attacks an attempt to thwart the peace process in Donbas and declared his intention to respond decisively to such aggression.
