Iran live updates: Trump threatens Iran infrastructure strikes if talks fail

The speaker of the Iranian parliament, Mohammad Bagher Ghalibaf, said in a statement on Sunday that Iranian forces are preparing for a U.S. ground operation despite ongoing diplomatic maneuvers.

"The enemy openly sends messages of negotiation and dialogue and secretly plans a ground attack," Ghalibaf said in a message addressed to the Iranian people on the 30th day of the war, the semi-official ILNA news agency reported Sunday.

Ghalibaf said that Tehran will continue its regional attacks, adding that the Iranian military is "waiting for the arrival of American soldiers on the ground to set fire to them and punish their regional partners forever."

"These days, we hear different words and statements from enemy officials about negotiations. America expresses its desires and announces what it has not achieved in the war as a list of 15 points and seeks them in diplomacy," Ghalibaf said.

"As long as the Americans seek Iran's surrender, your children's response to these American aspirations is clear: 'We will not accept humiliation,'" he added.

At least 3,461 people have been killed in Iran by U.S.-Israeli strikes since the war began on Feb. 28, the U.S.-based Human Rights Activists News Agency (HRANA) reported on Saturday.

The reported toll includes 1,551 civilians and 1,208 military personnel, while the status of 702 victims remains undetermined. According to HRANA, 236 of the victims were children.

ABC News cannot independently verify HRANA's data. However, HRANA has been reliable in counting deaths during previous rounds of unrest in Iran. HRANA says their data is collected from a combination of field reports, local contacts, medical and emergency sources, civil society networks and open-source materials -- including publicly available images, videos and official statements.

Official Iranian government channels have not been providing regular or comprehensive casualty figures from the current conflict. But the Iranian Health Ministry said on Saturday that 244 women and 231 children have been killed in the war so far, in a statement carried by the Islamic Republic News Agency.

The Bahrain Defence Force said on Sunday that its air defenses intercepted another six drones launched from Iran during the previous 24 hours.

Bahrain's interception tally since Feb. 28 is now 391 drones and 174 ballistic missiles, the force said.

Israel Defense Forces spokesperson Lt. Col. Nadav Shoshani told a press briefing on Sunday that strikes on Iranian weapon production and nuclear facilities are now the priority of IDF operations.

Shosahni said that on Saturday, Iran fired fewer than 10 ballistic missiles toward Israel while Hezbollah launched dozens of drones and rockets from Lebanon. Shosahni said that 90% of Saturday's attacks were intercepted.

Shoshani described the IDF ground operation inside southern Lebanon as "defensive," although Israeli officials have said their forces intend to seize additional Lebanese territory as a "buffer zone" to protect northern Israel from Hezbollah fire. Shosahni said that 850 Hezbollah members -- many from the elite Radwan Force -- have been killed in recent clashes.

Shoshani defended the IDF's Saturday killing of journalist Ali Shuaib, who he claimed -- without providing any evidence -- was a member of the Radwan Force. Shosani did not comment on the killing of two other Lebanese journalists -- Fatima Ftouni and Mohamed Ftouni -- on Saturday.
