Iraq says risk to Mosul dam affecting anti-Islamic State drive
The risk of Iraq's largest dam collapsing and unleashing a huge wave onto Mosul is affecting plans to retake the city from jihadists, an adviser to the prime minister's office said.
Baghdad: The risk of Iraq's largest dam collapsing and unleashing a huge wave onto Mosul is affecting plans to retake the city from jihadists, an adviser to the prime minister's office said.
The Iraqi army is deploying thousands of soldiers to a northern base in preparation for operations to recapture the northern city, the largest urban centre in the Islamic State group's self-proclaimed caliphate.
Concern has grown that a failure of the unstable dam, which stands about 40 kilometres northwest of the city, could wipe out most of Mosul and flood large parts of Baghdad.
The Americans "frequently refer to Katrina" and say a collapse of the Mosul Dam would be "a thousand times worse", an adviser to the office of Prime Minister Haider al-Abadi told reporters.
Hurricane Katrina ravaged the US city of New Orleans in 2005, killing nearly 2,000 people and leading to a wave of violence and looting that completely overwhelmed the authorities.
"If the dam busts, the centre of Mosul goes under water by about 12 to 15 metres," the adviser said, speaking on condition of anonymity.
"It just disappears, so 500,000 people (are) killed within a few hours," he said.
He said another dam in Samarra, hundreds of miles downstream, would also burst. It is estimated the wave would still be several metres high when it reaches Baghdad.
A US assessment published on the Iraqi parliament's website yesterday said Mosul dam was "at a signficantly higher risk of failure than originally understood."
Since the dam's completion in 1984, the Iraqi government has sought to shore up the foundation by injecting mortar-like grout into cavities that develop under the structure.
Regular minor seismic activity in the dam area is now seen as a potential threat.
As Iraqi forces backed by the US-led coalition ramp up preparations for an offensive against IS in Mosul, fears are also growing that the jihadists could weaponise the dam.
"If the attack on Mosul goes well, there is a nightmare scenario that Daesh (an Arabic acronym for IS) could itself strike the dam as they withdraw from Mosul," the adviser said.
