KYIV -- The Security Service of Ukraine (SSU) admitted on Saturday that it implemented "certain measures" linked to the explosion on the Crimean Bridge in October 2022.

"According to our legislation, international legislation and the customs and traditions of warfare, taking into account the fact that it was a logistical route that we were obliged to cut off the enemy, certain measures were taken," Vasyl Malyuk, head of the SSU, said in a statement published on the agency's website.

Still, it is too early to make public the details of the "special operation," Malyuk said.

On Oct 8, 2022, a deadly blast hit the 19-km Crimean Bridge, which consists of two parallel routes for automobiles and trains over the Kerch Strait.

A truck exploded on the road bridge, causing seven fuel tanks of a train heading to the Crimean Peninsula to catch fire. Three people were killed in the blast, which also led to the partial collapse of two spans of the road bridge.
