Natalie Portman refuses to attend ceremony for Israeli million-dollar prize

Hollywood actress Natalie Portman has refused to attend a ceremony in Israel to accept a million-dollar prize because of "recent events" in the country, the organisers said, announcing the prizegiving had been cancelled.

Israel has drawn international criticism in recent weeks for lethal tactics used during clashes with Palestinians along the border with Gaza. Thirty-one Palestinians have been killed and hundreds more wounded. Israel says it is doing what it must to defend its border.

In a statement on its website, the foundation that awards the Genesis Prize quoted a representative for Portman as saying: "Recent events in Israel have been extremely distressing to her and she does not feel comfortable participating in any public events in Israel."

It gave no further details of her reasons. An email to Portman's publicist in Los Angeles seeking further information was not immediately answered.

The Genesis Prize has been awarded since 2014 to individuals for excellence in their professional fields and "who inspire others through their dedication to the Jewish community and Jewish values".

Previous winners have included former New York Mayor Michael Bloomberg, sculptor Anish Kapoor, violinist Itzhak Perlman and Hollywood actor Michael Douglas, all of whom donated their prize money to charitable causes.

Portman was born in Jerusalem and moved to the United States at age three.
