AMSTERDAM, Netherlands — A website where a Dutch legislator was promoting an upcoming film that criticizes the Qur'an has been suspended by its U.S. hosting service.

The site had shown Geert Wilders' film's title, "Fitna," the words "Coming Soon" and an image of a gilded Qur'an. Now it shows a note that the company is investigating whether the site violates the firm's terms of service.

Wilders has not described the 15-minute movie, due to be released by March 31, in detail but has said it will underscore his view that Islam's holy book is "fascist."

Dutch officials fear the movie could spark violent protests in Muslim countries, similar to those two years ago after the publication of cartoons of the Prophet Muhammad in a Danish newspaper.

Wilders said he would release his movie on the Internet after television stations refused to air it.

"In this situation with the dialogue that's happening throughout the world we've made the choice to suspend the site as of last night," said Susan Wade, spokeswoman for Network Solutions. "This site is suspended so people can't see the content right now but the customer still has access to their site. They can make whatever changes are necessary as we complete our investigation."

Wilders, who lives under police protection due to death threats, could not immediately be reached for comment Sunday.

"How many ways are there left for me to be worked against?" he was quoted saying Saturday night by Dutch press agency ANP.

"If necessary, I'll go hand out DVDs personally on the Dam," he said, referring to Amsterdam's central square.

Thousands demonstrated on the Dam against Wilders' film Saturday in a protest intended to show that he does not represent the whole country.

Wilders heads a reactionary party with nine seats in the 150-member Dutch parliament, elected on an anti-immigration platform.

Network Solutions' terms of service contain a sweeping prohibition against "objectionable material of any kind or nature."

A Dutch court will hear a complaint lodged by Muslim groups seeking to bar Wilders from releasing the film March 28, but there is no legal barrier preventing Wilders from releasing his film before then.
