Gaza's children suffer post-conflict trauma

It's been three weeks since Suzy Eshkuntana was pulled from the rubble of her house in Gaza.

Destroyed by an Israeli air strike. Her mother and four siblings are under the rubble.

The six-year-old girl has barely spoken since, except to ask for her family, who were killed that day.

Suzy and her father are now living with her uncle, who said she barely eats, doesn't sleep well and doesn’t play.

"She doesn't speak a lot, I am her uncle and she used to stay at my home a lot, she used to speak a lot, to be very active, she was a naughty girl. But after their home was hit and her mother was killed the girl doesn't talk a lot, doesn't play a lot and she screams whenever people reach out to her, even myself, her uncle, whom she used to spend a lot of time with. She screams when I get close to her."

Half of young people in Gaza - around 500,000 children - could be in need of psychological support.

That’s according to officials from the U.N. children's fund UNICEF, who say 11 days of fighting in May between the enclave's Hamas rulers and Israel has left children traumatized.

Suzy's home was struck in a wave of Israeli attacks on Gaza City on May 16.

Gaza health officials say those attacks killed 42 people, including 10 children.

Israel said those strikes targeted an underground tunnel system used by Hamas to transport weapons. And that the houses collapsed as a result of the tunnel network crumbling.

Psychologists have paid Suzy regular visits to help her process her trauma.

Psychiatrists say depression and insecurity are the most common psychological issues they see here.

Around half of Gaza's population of two million are under 18.

Many carry the trauma of three previous wars and several other violent conflicts fought between Israel and Gaza militant groups since 2008.
