We're learning more about the Ukrainian raid in the Crimean village of Mayak, and it appears it was part of one of Ukrainian forces' most complex and ambitious operations to date against Russian military facilities on the Crimean Peninsula.
The operation involved Ukrainian special forces landing on the western shore of Crimea, near the settlements of Olenivka and Mayak, to attack Russian units, destroy Kremlin materiel and raise the Ukrainian flag.
Ukraine's Defense Intelligence Directorate said it carried out the attack in a joint operation with the Ukrainian Navy. The directorate released several videos purporting to show Ukrainian inflatables close to the Crimean coast in the darkness.
There's been no word from the Russian-appointed authorities in Crimea on the attacks.
The area targeted by Kyiv contains extensive Russian air defenses and missile sites, including advanced systems. Mayak is said to be home to a Russian radio engineering regiment and sophisticated radar.
It is the second time in two days that Ukrainian forces have targeted Russian weaponry in the area. Kyiv said Wednesday its forces had destroyed an S-400 missile defense battery in the area.
Reports from social media: Unofficial Russian social media accounts have spoken of firing near a campsite at Cape Tarkhankut -- the westernmost point in Crimea -- before dawn on Thursday. One channel said the first shooting broke out shortly before 4 a.m.
"When people woke up and came out of the houses and tents to the beach, they saw two rubber boats not far from the shore. There were 10 unidentified men in them. One of them fired at the camping site," according to the channel SHOT on the messaging app Telegram.
A prominent Russian military blog, Wargonzo, reported that, "according to some sources, a Ukrainian sabotage and reconnaissance group landed in the area of Cape Tarkhankut, shelled the camping on the seashore and fled in the direction of Odesa."
A Telegram channel associated with a military unit of the self-declared Donetsk People's Republic also reported the clashes. It said that four Ukrainian boats were destroyed near Cape Tarkhankut and 15 to 20 people were killed.
