Russian President has accused Ukraine of attacking the bridge to Russian-annexed Crimea, saying that it was an “act of terrorism”, writes BBC.

Vladimir Putin said Ukraine’s intelligence forces had aimed to destroy a critically important piece of Russia’s civil infrastructure. He was speaking at a meeting with the head of the Investigative Committee of Russia, Alexander Bastrykin.

Officials say three people were killed in the blast on the bridge. The victims were in a nearby car when a lorry blew up, Russian officials say.

“There is no doubt, this is an act of terrorism aimed at destroying Russia"s critical civilian infrastructure. Its authors, perpetrators and beneficiaries are the security services of Ukraine”, - Mr Putin said.

Bastrykin said that citizens of Russia and some foreign states had aided preparations for the attack: “Investigators have established that the truck which they say blew up travelled through Bulgaria, Georgia, Armenia, North Ossetia and Krasnodar Territory”.
