US warns of ‘tsunami wave’ across Iraq if the Mosul Dam collapses

Iraq’s Mosul Dam faces “unprecedented” risk of a “catastrophic failure” that would unleash a wave of water which could flatten cities and kill hundreds of thousands within hours, the US has said.

The American government issued an unusually stark warning of the horrors that face Iraq if the dam gives way, describing a “tsunami-like wave” that would crush nearly a third of the country.
