Iran has ruled out negotiations with the United States and warned citizens against any cooperation with Washington or Israel as the conflict intensifies.

Mohammad Mokhber, a senior aide to the late supreme leader, said Iran has no intention of engaging in talks with the US and maintains no form of contact with Washington, report Al Jazeera.

“We have no trust in the Americans, and we have no basis for any negotiations with them,” Mokhber said on Iranian state television. He added that Tehran is prepared to continue the war “as long as we want.” Mokhber previously served as Iran’s acting president and first vice president.

Separately, Iran’s judiciary chief Gholam Hosseini Mohseni Ejehe warned the public against expressing support for the United States or Israel during the ongoing war.

“We have announced that those who cooperate with the enemy in any way will be considered an enemy,” Ejehe said in remarks broadcast on state television. He stressed that individuals who “say or do anything in line with the will of America and the Zionist regime” would be treated as siding with the enemy and dealt with under what he described as “revolutionary, Islamic principles” appropriate to wartime conditions.

The warnings come after both the US and Israel publicly called on Iranians to rise up against their government. Former US President Donald Trump said the conflict could represent the Iranian people’s “only chance for generations” to overthrow the leadership.

Earlier this year, nationwide protests in Iran resulted in thousands of deaths, according to UN officials and international human rights organizations, which documented widespread use of deadly force against demonstrators.

The latest statements signal Tehran’s firm stance against external pressure and suggest continued domestic crackdowns as hostilities with the US and Israel persist.
