Israeli Prime Minister Benjamin Netanyahu said on Sunday Israel would continue acting against the Iran-backed Houthis in Yemen, whom he accused of threatening world shipping and the international order, and called on Israelis to be steadfast.

“Just as we acted forcefully against the terrorist arms of Iran’s axis of evil, so we will act against the Houthis,” he said in a video statement a day after a missile fired from Yemen fell in the Tel Aviv area, causing a number of mild injuries.

On Thursday, Israeli jets launched a series of strikes against energy and port infrastructure in Yemen in a move officials said was a response to hundreds of missile and drone attacks launched by the Houthis since the start of the Gaza war 14 months ago.

On Saturday, the US military said it conducted precision air strikes against a missile storage facility and a command-and-control facility operated by Houthis in Yemen’s capital, Sanaa.

Netanyahu, strengthened at home by the Israeli military’s campaign against Iran-backed Hezbollah forces in southern Lebanon and by its destruction of most of the Syrian army’s strategic weapons, said Israel would act with the United States.

“Therefore, we will act with strength, determination and sophistication. I tell you that even if it takes time, the result will be the same,” he said.
