I suspect it was either a test launch or mass hallucination by Iraqi channels.

High threat of Oniks supersonic cruise missile launches to Odesa from Crimea

Oniks missile to Odesa

2 missiles

Flying to Zatoka/Chornomorsk

2 Su-34s and 2 Su-35s over Sevastopol. They may launch Kh-59/69 cruise missiles to Odesa.

Missiles are 120 km from the coast

Right now they are flying to Karolino-Buhaz, Odesa Oblast. 40 km from the coast.

Over the coastline. Flying to Bilhood-Dnistrovskyi

They disappeared. Explosions were reported.

2 Kh-59/69 cruise missiles were launched from the Su-34s, flying to Yuzhnyi Port, Odesa Oblast.

50 km from the coast, flying to Odesa City/port now.

These look like secondary detonations.

Local channels report ongoing secondary detonations at the site of the explosion in Khmelnytskyi.

Ukrainian journalist Yuliya Kyriyenko reports that the supply of mobilised men to the 425th Assault Regiment "Skala" and the 1st Assault Regiment has been temporarily suspended by the new Ukrainian Commander-in-Chief Mykhailo Drapatyi.

Additionally, at the 225th Assault Regiment, mobilisation for the unit through the TCC has stopped, although men mobilised prior to this are still arriving for the time being.

These three units were part of former Commander-in-Chief Syrskyi's "personal assault army", and had a total priority for newly mobilised men, resulting in significant understaffing issues for other units. This could indicate Drapatyi intends to decrease the size of these units, which at the moment are over 50,000 strong despite only having the "regiment" status, and reform the structure and layout of them back to more "conventional" units.
