Above: Remains of the police chopper after it was shot down by gang.
At least 32 people have been killed since last Saturday in Rio de Janeiro
The fighting erupted at the weekend when a police helicopter was shot down by suspected drug traffickers. Police interrupted the gun battles between drug gangs before this tragedy.
The violence comes just weeks after Rio was chosen to stage the 2016 Olympics.
Feuding between rival drug gangs across several shantytowns (above the burning bus in one of the shanty towns) in the north of Rio that began on Saturday seems to have started a grim sequence of events that has yet to reach a conclusion, says the BBC's Brazil correspondent Gary Duffy.
This level of crimes......., it seems the 2016 olympic people have to go with bullet and grenades-proof vests!!
