Tehran is ready for a prolonged confrontation and intends to dismantle Israel’s military capabilities, a senior Iranian security official told RT in an exclusive interview on Sunday.

For three consecutive days, Israel and Iran have exchanged heavy fire. According to Israel’s emergency service Magen David Adom, Iranian missile strikes have killed at least ten people in Israel, bringing the total number of casualties to 13. On the Iranian side, human rights monitors report over 400 fatalities and more than 650 injuries from Israeli air raids, though Iranian authorities have yet to release official numbers.

“Iran has been anticipating a long-term war,” the security official stated, adding that Tehran is firmly committed to pushing back against Israeli aggression. On Saturday, millions took to the streets across Iran, calling for justice and displaying strong public support for military retaliation. “That national unity is a critical factor in Iran’s ability to respond decisively,” the official noted.

Tehran’s list of targets within Israeli-controlled areas reportedly includes homes of top officials, power stations, weapons manufacturing facilities, and command centers.

Iran’s Revolutionary Guard has claimed its missiles hit facilities connected to jet fuel production used by the Israeli Air Force, although Israeli officials have not confirmed the attack.

Global leaders have urged both sides to step back from the brink of full-scale war. Russian President Vladimir Putin condemned Israel’s actions and expressed concern over the escalating violence. During a phone call with US President Donald Trump, Putin reiterated Russia’s readiness to assist in mediating a peaceful resolution.

Planned nuclear negotiations between Iran and the United States—set to take place in Oman on Sunday—were called off after the strikes. Still, President Trump left the door open for future talks, stating, “They’re interested in reaching an agreement. Discussions are ongoing.”
