PHILADELPHIA — Hillary Clinton’s campaign condemned the burning of an Israeli flag at the Democratic National Convention.

“Hillary Clinton has always stood against efforts to marginalize Israel and incitement, and she strongly condemns this kind of hatred,” Sarah Bard, the campaign’s director of Jewish outreach said in an email Wednesday.

“Burning the Israeli flag is a reckless act that undermines peace and our values.”

An Israeli flag was set alight Tuesday as protesters chanted “Long live the intifada” outside the Wells Fargo Arena in Philadelphia, housing the Democratic National Convention.

Protesters chanted “Long live the intifada” and a woman wearing a black bandanna on her face lit the flag on fire. Someone stood nearby waving a Palestinian flag.

In a possible riposte to the flag-burners, Bill Clinton wore a Hebrew “Hillary” pin on his jacket at the convention on Wednesday.
