Iranian parliamentarians are preparing a bill that could push Tehran toward exiting the nuclear Non-Proliferation Treaty, the foreign ministry said on Monday, while reiterating Tehran's official stance against developing nuclear weapons.

The Israeli military has damaged critical nuclear infrastructure and killed scientists, but Tehran’s most formidable enrichment plant remains.

Smoke and flames filled the sky over Tehran as Israel struck oil and gas facilities in the Iranian capital and targeted more nuclear facilities during attacks that carried on into Sunday after starting two days earlier.

Three people have been killed in Israel, according to officials and local media, with both sides saying the strikes will continue.

There will be no nuclear talks with Iran on Sunday, a senior U.S. administration official says, adding Washington still hopes Tehran will resume negotiations soon. “We remain committed to talks and hope the Iranians will come to the table soon,

Iran has warned it will ramp up its nuclear activities after the United Nations nuclear watchdog’s 35-member board of governors adopted a resolution Thursday declaring it in breach of its non-proliferation obligations.
