Iranian President Masoud Pezeshkian warned that his country would retaliate "strongly" for any attacks on its infrastructure.
"We have stated many times that Iran does not carry out preemptive attacks, but we will respond decisively if our infrastructure or economic centers are attacked," he wrote in X.
The Iranian president also warned countries in the Middle East region that if they want development and security, they must not allow "our enemies to wage war from their lands".
Separately, Pezeshkian told Pakistani Prime Minister Shehbaz Sharif that trust was needed to facilitate negotiations and mediation in the Middle East conflict, Reuters reported.
He praised Pakistan's diplomatic efforts, and the two leaders discussed military actions in the region and efforts to end the conflict during a call that lasted more than an hour.
Sharif informed Pezeshkian on Pakistan's diplomatic contacts with the United States and the Gulf States.
