Polish police found a crater and scattered debris in a field left by ​an unidentified object that disappeared from army radars tracking ‌it in domestic airspace during Russian strikes on Ukraine.

Axar.az reports, citing Reuters, that Poland scrambled fighter jets to secure its airspace after Russian air strikes ​killed at least 13 in neighbouring Ukraine, including one ​in Kyiv, the capital, in attacks that spread ⁠as far as the western city of Lviv.

"An unidentified object ​moving westward was detected in Polish airspace," the operational command ​of the armed forces said on X, adding that it disappeared from radars soon after the sighting at 3:40 a.m.

A Mi-24 helicopter that went ​to the object's last location to verify and confirm ​the radar data pinpointed the likely crash site, it added.

"A helicopter crew ‌located ⁠the probable crash site of the object in an undeveloped area near the village of Tarnawa-Kolonia in the Lublin province."
