Russian President Vladimir Putin will hold an operational meeting of his Security Council on Monday, just two days after a massive explosion on a key strategic bridge linking Crimea and Russia.Kyiv has not claimed responsibility for the blast on the enormous 19-kilometer (about 12-mile) bridge, which was built after Moscow annexed Ukraine’s Crimean Peninsula in 2014, an annexation regarded by the West as illegal.” The crossing was opened by Putin himself in 2018, and Ukrainian reaction to the explosion has been gleeful and triumphant.Putin called the explosions on the Crimean bridge a “terrorist attack” and said the organizers and executors were “Ukrainian special services.”“Here, as reported, we have no doubts that this is a terrorist attack aimed at the destruction of the critical infrastructure of Russian Federation.And authors, executors, and masterminds are the secret services of Ukraine,” Putin said during a meeting with Chairman of the Russian Investigative Committee Alexander Bastrykin on Sunday.But with a sudden and successful Ukrainian offensive comes concerns Putin will escalate Russia’s war in Ukraine, with US President Joe Biden expressing fears of the possible use of weapons of mass destruction."
