MOSCOW, August 5. /TASS/. The terrorist attacks committed by Kiev will not remain without response, and their masterminds will be held accountable, Russian Foreign Ministry Spokeswoman Maria Zakharova said in a statement, commenting on the Ukrainian terrorist attack against a Russian civilian ship in the Kerch Strait.

"Such barbaric actions cannot be justified and they will not remain without response, while their authors and perpetrators will inevitably be held accountable," the diplomat said.

Zakharova emphasized that Russia strongly condemns the terrorist attack which not only put the lives of the crew in danger, but also posed the threat of a large-scale environmental disaster.

"Facing no condemnation from the Western countries and international organization, the Kiev regime is busy applying more and more new terrorist techniques, this time in the waters of the Black Sea," the diplomat added.

The Russian Foreign Ministry spokeswoman pointed out that Ukraine’s Security Service (SBU) had in fact claimed responsibility for the terrorist attack, as its Chairman Vasily Malyuk, as Zakharova indicated, described "with the inhumanity typical of Ukrainian Nazis" the attack designed to kill unarmed civilians as "a legitimate, logical and effective step."

"The international community can once again see for themselves what kind of ‘legality’ Kiev professes," she added.

Early in the morning on August 5, the Sig tanker was attacked by Ukraine when approaching the Kerch Strait from the south. The vessel was stove in near the engine room at the waterline on the starboard side. The Maritime Rescue Coordination Center of Novorossiysk told TASS earlier that there was no oil spill.
