Horror as screaming children, 11 & 12, are savagely attacked by 2 pit bulls as adults try to fight them off with sticks

HARROWING footage shows the moment two angry pit bulls savagely attack children inside a playground in a horrific attack.

A fun day turned into a devastating nightmare when one kid was yanked off a slide by the savage beast as it devoured the child's leg.

Horror footage shows two rampaging pit bulls rushing inside a playground before attacking the children as bystanders scream at the top of their voices.

A 12-year-old girl and a boy, 11, were seen desperately trying to protect themselves from the dogs, sitting on a climbing frame in the playground in Sao Paulo, Brazil.

One of the raging dogs can be seen clamping its razor-sharp jaws around the boy's legs.

Despite trying to shake off the dog, the child is unable to do so and he slides off the climbing frame with its jaws still chomping down on the screaming boy's leg.

He desperately tries to fight it off but the weight of the dog is too much and he falls to the ground where the dog continues to attack him.

After surviving some 10 seconds of the horror ordeal, he is finally able to free his leg but the dog immediately bites down on one of his arms.

One of the adults tries to beat the dog away with a long stick but it breaks.

Finally, the child manages to free his arm and he places himself on top of the dog to avoid it biting him again.

The other dog meanwhile approaches as if ready to attack with the child's face dangerously close to its jaws as the footage ends.

Local media reports said that both the kids were seriously injured after the two pit bulls attacked the playground.

They have not been named.

Cops said the girl suffered deep cuts to her arms, head, hands and chest.

She was rescued by police officers and taken to hospital where she was treated and discharged.

Meanwhile, the boy suffered much worse injuries and had to be transferred to a different hospital.

He is now said to be in a stable condition.

Cops have now opened an investigation to identify the owners of the dogs.

It is currently unclear what happened to the dogs after the end of the footage.
