A vast Soviet-era dam in the Russian-controlled part of southern Ukraine was blown on Tuesday, unleashing a flood of water across the war zone, according to both Ukrainian and Russian forces.
Both sides blamed the other for destroying the dam.
Unverified videos on social media showed a series of intense explosions around the Kakhovka dam. Other videos showed water surging through the remains of the dam with bystanders expressing their shock, sometimes in strong language.
