Pro-Israel ads have been installed in the Washington, D.C., Metro system after on a judge's recent decision to allow them.

The one-page ruling from U.S. District Judge Rosemary Collyer follows a similar court order in New York that cited freedom of speech. It cleared the way for anti-jihad ads to go up in that city's subway system last month.

The ads have caused a stir because they equate Muslim radicals with savages.

"In any war between the civilized man and the savage, support the civilized man. Support Israel. Defeat Jihad," the ads state.

"The result is absolutely correct," said David Yerushalmi, a lawyer representing the American Freedom Defense Initiative, the organization behind the advertisements.

"There simply was no way under the First Amendment jurisprudence that we have today that this ad should not have gone up when contracted," he said.

Metro officials fought the ad, saying they might spark violence like the violent reaction in Middle East to the online video, "Innocence of Muslims."

The New York ads went up in 10 stations across Manhattan on Sept. 24. Since then, an Egyptian-born U.S. columnist and pundit for CNN and MSNBC was arrested for spray-painting the ad.

The ads have prompted officials to sell space to accommodate for counter, pro-Muslim messages.
