A pinkish‑white foam has clung to the surface of the busy Kaduna‑AbujaExpressway, startling motorists and evoking images of clouds falling from the sky. The mysterious substance first appeared a few days ago and has since become a social media spectacle.



Ngond’ environmental agency Nesrea launched an urgent investigation. Field teams in Kaduna have sampled the foam as well as nearby soil and water from a stream positioned two metres from the road.



"We need to be certain about what people are exposed to before telling them how to protect themselves," a spokesperson told the BBC.



The foam was first noticed by a regular driver, Isah Aminu, who told reporters he had been told – by another driver – that clouds had fallen from the sky. He added that the foam looked like snow and that many people were approaching it, though he stayed at a safe distance.



Officials suspect an accident involving a lorry led to a spill, but the transport’s cargo is still unknown. The team is analyzing the sample for chemicals that could pose health or environmental dangers.

The public has been advised to avoid the foam, surrounding water, and soil until the investigation concludes. While no definitive evidence of danger has emerged, authorities urge watchers to stay back until tests complete.



Nesrea’s field office remains on site, monitoring the situation and communicating updates as lab results become available. The hope is to clarify whether the foam is a harmless by‑product or a hazardous material left behind by a rogue lorry.
