A girl walks past riot policemen guarding one of the access roads to Benito Juarez International airport after demonstrators staged a protest over the 43 missing Ayotzinapa students in Mexico City November 20, 2014. Forty-three missing students abducted by corrupt police in southwest Mexico weeks ago were apparently incinerated by drug gang henchmen and their remains tipped in a garbage dump and a river, the Mexican government said.
