The article says the Iraqi government has hired an Italian contractor to reinforce and maintain the dam. This presumably makes the massive-disaster scenario described in the Guardian's rather clickbaity headline somewhat less likely.

Edit: fair enough, it might not be as simple as just hiring some engineers to fix it; I hadn't considered the location. But still: when the news event that happened yesterday is that some engineers were hired to fix the dam, I think it's a bit disingenuous to therefore run a story with a headline saying "dam on brink of collapse, may kill one million."
