A railway bridge in Russia’s Samara region was damaged due to an explosive device, the Tass news agency reported on Monday.

Railway traffic over the bridge has been suspended because of “illegal interference”, the railway authorities said earlier.

No information about casualties has been reported.

It comes as Russia’s foreign ministry on Monday summoned the German ambassador, the Tass news agency reported, citing an unidentified source, after Russian media published an audio recording of a meeting of senior German military officials.

In the purported call, German officers were heard discussing weapons for Ukraine and a potential strike by Kyiv on a bridge in Crimea, prompting Russian officials to demand an explanation.
