An Israeli hospital is treating a cancer-stricken Iranian boy.

The 12-year-old boy is being treated at the Sheba Medical Center near Tel Aviv for a large brain tumor, after treatments in Iran and Turkey failed. Israel granted the child a special permit to enter and he arrived on a flight on Friday.

Iran and Israel are bitter enemies and have no formal relations. Iran's president has denied the Holocaust and repeatedly called for Israel to be "wiped off the map."

Sheba CEO Zeev Rotstein said the child had a very aggressive tumor but he hoped the hospital's expertise would give the boy a better chance of survival than he would have had in Iran.

He also said he hoped that news of the Israeli doctors efforts would help pave the way to understanding between people.
