Patience of the international community over talks on Iran's nuclear program is not endless, German Foreign Minister Frank-Walter Steinmeier said here on Thursday.

Speaking to the German parliament on government policy before the two-day European Union summit on Dec. 15-16, Steinmeier urged Iran not to delay the dispute over its nuclear research.

"I say again: The government in Tehran must understand that the patience of the international community is not endless," Steinmeier said.

European Union leaders will address Iranian President Mahmud Ahmadinejad's denunciation of the Holocaust as a "myth," he said, warning that patience is running out with Tehran.

The German government has condemned the remarks by Ahmadinejad and called on the United Nations as well as the EU to follow suit.

Berlin says the comments will also weigh on talks over Tehran's disputed nuclear program.

The anti-Jewish comments made a solution to the nuclear issue more difficult, he said, adding that Ahmadinejad's remarks were unacceptable.

The remarks showed "with how much irresponsibility and cynicism the Iranian government currently regards the situation of Israel and the Near East," he said.

Germany, France and Britain have been negotiating with Iran in an attempt to persuade it to give up its nuclear program. Later this month, Iran is due to resume negotiations on the issue with envoys from the three countries.

Ahmadinejad's comments about Jews and Israel have grabbed headlines across the world over the past few months.

He first provoked an international outcry in October when he called for Israel to be "wiped off the map." He then expressed doubt about the Nazi destruction of European Jews during World War II and went further on Wednesday by saying that the Holocaust is a "myth" that Europeans have used to create a Jewish state in the heart of the Islamic world.
