After the Crimean bridge attack, there are plenty of theories but few real answers

Transcript¹

KYIV, Ukraine — Nearly a week after an explosion damaged a vital bridge in Crimea, Russian and Ukrainian authorities are still trading accusations² and offering competing theories as to what and who caused the blast. But definitive³ answers remain elusive⁴.

On Wednesday, Russia's Federal Security Service arrested eight men alleged⁵ to have taken part in an elaborate scheme to destroy the Crimean bridge. Investigators⁶ said Ukrainians, Russians and an Armenian camouflaged⁷ tons of explosives and shipped them to several countries before Saturday's attack. Russia says a driver with no previous connections to terrorism drove a truck bomb onto the bridge at a time to maximize damage.

But Mykhailo Podolyak, a top adviser⁸ to Ukrainian President Volodymyr Zelenskyy, says Ukrainian intelligence believes that Russian forces planned the attack as a pretense⁹ to escalate¹⁰ the war in Ukraine.

"The Crimea bridge incident gives the Russian military a convenient alibi¹¹ for all of its defeats in southern Ukraine," Podolyak told Ukraine's national broadcaster.

Many theories, but little certainty

Credible¹² theories abound¹³ in Ukraine and abroad about who is responsible for the Oct. 8 attack and how they did it. But, says Andrew Barr, an impact dynamics¹⁴ researcher at the University of Sheffield, "Despite all of the publicly available photos and videos, it's quite difficult to be certain about this."

Surveillance video posted by Russian media shows a single truck driving from mainland Russia toward Crimea before a flash of light swallows he bridge. Photos posted by independent media outlets¹⁵ show at least three collapsed¹⁶ road spans resting crookedly¹⁷ on piers¹⁸ in the shallow water.

New photos posted on social media Wednesday show bent¹⁹ support beams on the Russia-bound lanes as well. That side of the bridge reopened to traffic only hours after the blast.

Nick Waters, an analyst²⁰ with the digital forensics firm Bellingcat, points out that the bridge's underside shows barely any blast damage, dismissing a popular Ukrainian theory that a special naval²¹ operation destroyed the bridge from below.

Unlike the bridge's unscathed bottom, satellite images released by Maxar Technologies show a blackened road top.

Soon after the explosion, Ukrainian experts quickly dismissed the notion that a Ukrainian missile had targeted the bridge, citing the 180-mile distance from Ukrainian-held territory as a technical limitation. The United States and other countries that supply weapons to Ukraine have refused to provide missiles that travel that far.

FSB published a video of an "examination of the truck" and its "X-ray", which allegedly shows explosives.

After Russian state media posted the government's evidence for a truck bomb — the alleged truck involved and a X-ray scan of its cargo²² — Ukrainian journalists pointed²³ out that the two images showed different trucks.

Still, some military experts believe that a truck bomb is the likely culprit, even if those responsible for it are harder to determine.

"The damage is definitely consistent with an explosion in the center of a bridge span, as anything else would have caused damage to the pier," says Barr, who specializes in analyzing²⁴ blast damage in war zones.

He says the Crimean bridge is designed to have a single section of road floating above several piers and detached from other sections. When one span falls into the water, it pulls several other spans with it.

Based on the ways the flames repeatedly shot out from the blast site, Barr also suggests that the truck was loaded with specialized²⁵ compounds that burned hot enough to ignite a passing fuel train traveling on a parallel rail bridge, severely²⁶ weakening it.

Mika Tyry, a retired²⁷ military demolition²⁸ specialist, told YLE, Finland's national broadcaster, that the flames and sparks are consistent with a thermite bomb. Russia's military has been known to use thermite, though Ukraine could have recovered the substance from unexploded Russian munitions²⁹.

"It's a successful attack on a guarded structure, with advanced explosives, and timed with the train," Barr says. "That's highly suggestive of a carefully planned military operation rather than a lone³⁰ actor or other group."

Russian launched more strikes across Ukraine after the bridge attack

On Wednesday, Russian state media suggested that the Crimea bridge attack was coordinated³¹ from the United States to escalate what many Russians believe to be a proxy³² war against the West over Ukraine.

Ukraine has not taken credit for the blasts, though many in the country celebrated³³ it as a Ukrainian victory due to the bridge's strategic and symbolic³⁴ value to Russia.

Russian President Vladimir Putin launched a series of air strikes across Ukraine this week, saying it was a response to what he called "Ukrainian terrorism" on the Crimean bridge. Zelenskyy said more than 150 rockets and drones killed 20 people on Monday and Tuesday, knocking out essential services in more than half of Ukraine.

"That's not the kind of thing that the Russians can throw together in a couple days," National Security Council spokesperson John Kirby told CNN on Monday. "This was something not in retaliation³⁵, but was really much of a continuation of Putin's designs over the last several weeks to specifically target Ukrainian civilian³⁶ infrastructure³⁷."
