Mexican man feared dead after falling into mass of polluted suds

Excess detergents from homes that drain into streams feeding the Valsequillo reservoir caused suds to accumulate, authorities say

A Mexican man is feared dead after he posed for a photograph alongside a 6m-high (19.7ft) mass of soap suds on a heavily polluted stream - and apparently fell into the quivering mass.

Emergency teams in the central state of Puebla are still looking for the man, who fell into the mass of suds earlier this week.
