Russia says truck bomb damages bridge to Crimea

Russian authorities said Saturday that a truck bomb has caused a fire and the collapse of a section of a bridge linking Russia-annexed Crimea with Russia.

Russia's National Anti-Terrorism Committee said that the truck bomb caused seven railway cars carrying fuel to catch fire, resulting in a "partial collapse of two sections of the bridge." The committee didn't immediately apportion blame.

The attack on the bridge comes a day after Russian President Vladimir Putin turned 70, dealing him a humiliating blow that could lead him to likely to up the ante in his war on Ukraine.

The Crimean Peninsula holds symbolic value for Russia and is key to sustaining its military operations in the south. If the bridge is made inoperable, it would make it significantly more challenging to ferry supplies to the peninsula. While Russia seized the areas north of Crimea early during the invasion and built a land corridor to it along the Sea of Azov, Ukraine is pressing a counteroffensive to reclaim them.

The bridge has train and automobile sections. Russia's National Anti-Terrorism Committee specified that the explosion and fire led to the collapse of the two sections of one of the two links of the automobile bridge, while another link was intact.

Authorities have suspended commuter train traffic across the bridge until further notice. Putin was informed about the explosion and he ordered the creation of a government panel to deal with the emergency.

The 19-kilometer (12-mile) bridge across the Kerch Strait linking the Black Sea and the Sea of Azov is the longest in Europe. It has cost billions of dollars to build and it has provided an essential link to the Crimean Peninsula, which Russia annexed from Ukraine in 2014. Ukrainian officials have repeatedly threatened to strike the bridge.

In August, Russia suffered a series of explosions at an airbase and munitions depot in Crimea, which underlined its vulnerability.
