Shock video circulating online appears to show parts of Tehran drowning in waste after Israeli missiles struck water and sewage pipelines.
Footage shared on social media shows a street in the Iranian capital overflowing with water and waste product, creating a disgusting brown flow through the city.
The outbreak means that emergency services in Tehran are grappling with simultaneous challenges.
These include the impact of missile strikes, crumbling nuclear infrastructure, and now a public health nightmare as sewage seeps into streets.
The breakdown of potable water and sewage systems also risks triggering disease outbreaks and major social rest in an already volatile capital.
