Crimea bridge attack: What happened, why is the bridge important?

Traffic on the single bridge that links Russia to Moscow-annexed Crimea and serves as a key supply route for the Kremlin’s forces in the war with Ukraine came to a standstill on Monday after one of its sections was blown up, killing a couple and wounding their daughter.

The RBC Ukraine news agency reported that explosions were heard on the bridge, with Russian military bloggers reporting two strikes.
