At least four police officers have been killed, after their police helicopter was reportedly shot down by gang members, in Brazil.
Four police officers have died after their helicopter crashed over Rio de Janeiro’s notorious City of God favela.
In video footage of the crash, sustained gunfire could be heard before the helicopter drops from the sky, narrowly missing a main road.
The helicopter was giving support to a police operation against gangs in the favela, according to police.
Police reportedly began a large scale operation on Sunday in western Rio, with arrests and seizures of drugs.
