This is the incredible moment a firefighter rescued a baby from a burning building.

Amazing video footage from Buenos Aires, Argentina, shows a firefighter scaling the building with a baby in his arms in the dramatic rescue.

Using a harness, the man crosses over the wall of the balcony and lowers himself down the side of the building.
