"Israel is consolidating its deterrent power, it is striking at those who seek to harm it, it is collapsing Iran's terror branches one after the other," Benjamin Netanyahu told the Israeli Knesset.
Netanyahu said Tehran was still "busy licking the wounds from the blows we inflicted on them", adding he had instructed the Israeli military in recent days to attack strategic targets of Yemen's armed Houthi group in response to their missile launches at Israel.
"It is neither the first nor the last. We have destroyed significant terrorist assets that the Houthis have used, and the principle we have set is very simple – whoever tries to harm us, we will hit him with uncompromising force," Netanyahu added, according to a translation by the Israeli website Ynet.
The Israeli military and its American allies have launched multiple air raids against the Houthis' positions in recent days, but have failed to stop Houthi attacks on Israel.
The spokesman for the Houthis said the Iran-backed group launched two drone attacks against targets in Israel's Ashkelon and Tel Aviv on Monday.
Some Israeli officials believe their country must directly target the Islamic Republic, which has publicly declared its support for Yemen's Houthis.
