Iranian President Ebrahim Raisi issued renewed threats to Israel and the US after Israel launched a ground offensive in Gaza against Iran-backed Hamas.

"The Zionist regime's crimes have crossed the red lines, which may force everyone to take action," he said, suggesting once again the threat of action from its proxies in the region.

"Washington asks us to not do anything, but they keep giving widespread support to Israel," Raisi stated in his post on X on Sunday morning.

Iran's proxies have continued to target US facilities in the Middle East since the war declared by Hamas broke out on October 7 after its elite forces invaded Israel, killing at least 1,400 and kidnapping at least 230. Its Yemeni proxy, the Houthis, even fired rockets towards Israel, intercepted by the US and Saudi Arabia.

IDF spokesman Daniel Hagari confirmed the ground invasions, explaining they are being carried out "in a phased manner". He said, "This will take time."

Denying its hand in the ever heightening regional tensions, the Iranian president claimed its proxies are "independent" and "do not receive any orders from Tehran", blaming the US.
