Russia says it saw off 42 drones launched by Ukraine over the occupied Crimean peninsula overnight.
It comes one day after Ukraine claimed its troops briefly landed in Crimea to mark the country's independence day.
On Thursday, Ukraine marked the country’s Independence Day with a “special operation” in the occupied Crimean Peninsula, where its troops briefly landed overnight.
The defence ministry said all objectives were achieved without any casualties.
However, “the enemy suffered losses” during a firefight in Olenivka and Mayak, western Crimea, it said.
The intelligence department of Ukraine's defence ministry posted a video purportedly showing Ukrainian soldiers raising the national flag.
The Russian-installed governor of Crimea, Mikhail Razvozhayev says no civilian infrastructure was damaged by the alleged Ukrainian drone strike.
But he says the area is prepared for future attacks.
