Police in Brazil have discovered 10 tons of marijuana after battling drug dealers in the country's sprawling slums in Rio de Janeiro.

They are also searching for hundreds of traffickers who are believed to have fled Sunday's raid on one of the city's most dangerous slums.

Public health officials say about 50 people, most of them suspected drug traffickers, were killed in the weeklong operation. 

Gabriel Elizondo was there when police made one of their biggest seizures.
