UNITED NATIONS, Sept 27 (Reuters) - Iran responded to Israel's "red line" for Tehran's nuclear program on Thursday by declaring it was strong enough to defend itself and that it reserved the right to retaliate with full force against any attack.

In a response to a speech at the U.N. General Assembly by Israeli Prime Minister Benjamin Netanyahu, Iran's U.N. mission said Israel had made "baseless and absurd allegations against (its) exclusively peaceful nuclear program."

"While the use , or threat of use , of force under any pretext is a grave violation of the principles of ( the) U N Charter and international law, as well as the norms of international relations, the officials of the Israeli regime are so rude (th e y) on (a) dail y basis threaten countries in the region, particularly my country, (with) military attack," Iran said.

"The Islamic Republic of Iran is strong enough to defend itself and reserves its full right to retaliate with full force against any attack," the Iranian mission said in the written statement.
