Israel's military said Yemen had launched a missile toward Israel early Saturday morning, the first time it had faced fire from that country.
Sirens went off around Beer Sheba and the area near Israel's main nuclear research centre for the third time overnight Friday into Saturday as Iran and Hezbollah continued to fire on Israel overnight.
The Houthis, a rebel group backed by Tehran, have held Yemen's capital, Sanaa, since 2014. They did not immediately acknowledge launching an attack against Israel.
Israel struck Iran's nuclear facilities hours after threatening to 'escalate and expand' its campaign against Tehran on Friday. Iran vowed to retaliate and struck a base in Saudi Arabia, wounding US service members and damaging planes.
Attacks on vessels during the Israel-Hamas war upended shipping in the Red Sea, through which about USD 1 trillion worth of goods passed each year before the war.
The rebels also fired drones at Israel. Israel's military later said raw materials are processed for enrichment at the Yazd plant and the strike was a major blow to Iran's nuclear program.
