Flint's 'toxic soup' polluted water worse for children than thought, doctor says

• Dangerous levels of lead in 15% of children's blood in certain hotspots
• Dr Mona Hanna-Attisha discovered pollution that led to state of emergeny

The doctor who discovered that the children of Flint, Michigan, were at risk of irreparable brain damage from lead poisoning in the city's water supply has warned that the problem of "toxic soup" coming out of their household taps may have affected many more than originally thought.

All children under the age of six - between 8,000 and 9,000 of them - have been put in jeopardy by Flint's contaminated water.
