The United States says Iran has left the UN Security Council no choice, but to increase sanctions on the Islamic Republic for ignoring demands that it halt nuclear activities.

The US declaration came a day after an informal deadline lapsed for Iran to respond to an offer from the United States, Britain, France, Germany, China and Russia for talks on its disputed nuclear program.

Spokesman for America's mission to the UN Richard Grenell says it's clear the government of Iran has not complied with the international community's demand to stop enriching uranium and isn't even interested in trying.

Tehran has not formally responded to the offer, but President Mahmoud Ahmadinejad said on Saturday Iran won't back down.

The West accuses Iran of seeking to develop nuclear weapons under cover of a civilian power program.
