Israeli Prime Minister Benjamin Netanyahu issued a warning to Hezbollah following its alleged assassination attempt against him and his wife, calling it a "grave mistake."

"The attempt by Iran’s proxy Hezbollah to assassinate me and my wife today was a grave mistake," Netanyahu wrote in a X post Saturday. "This will not deter me or the State of Israel from continuing our just war against our enemies in order to secure our future."

Issuing a stark warning to Iran and the "Axis of Resistance," which includes Hezbollah, Hamas and the Houthis, the prime minister said Israel is determined to achieve its war objectives following the Oct. 7 attack and "change the security reality in our region for generations."

"I say to Iran and its proxies in its axis of evil: Anyone who tries to harm Israel's citizens will pay a heavy price; We will continue to eliminate the terrorists and those who dispatch them; We will bring our hostages home from Gaza; And we will return our citizens who live on our Northern border safely to their homes," he wrote.

"Israel is determined to achieve all our war objectives and change the security reality in our region for generations to come," Netanyahu said. 

Together, we will fight, and with God's help – together, we will win.
