Israel conducted airstrikes on the Houthi-controlled capital of Sana’a Thursday evening, targeting the main airport and multiple power stations following ongoing attacks on Israel by the Iranian-backed rebel group.

The strikes also hit Houthi military infrastructure at the ports of Al-Hudaydah, Salif, and Ras Kanatib on Yemen’s western coast.

The Israel Defense Forces said the targets included facilities used by the Houthi rebels to smuggle Iranian weapons and facilitate the entry of senior Iranian officials. The group has launched repeated attacks against Israel, employing drones and surface-to-surface missiles since the start of the Gaza War.

According to a Houthi spokesman, the strikes on Sana’a International Airport and the port city of Al-Hudaydah resulted in four deaths. A United Nations team preparing to board a flight at the airport was present during the attack, the UN confirmed in a statement.

Over the past week, the Houthis have fired ballistic missiles and drones at Israel four times. On Dec. 19, a Houthi missile caused a school building in Ramat Gan to collapse, prompting Israeli retaliatory strikes.

The latest operation marked the fourth instance since July that Israeli Air Force jets have flown more than 2,000 kilometers to target Houthi sites, and the second in a week. Israeli Prime Minister Benjamin Netanyahu reaffirmed Israel’s commitment to stopping the attacks, stating that the strikes would continue until the threat is eliminated.

The strikes coincided with a speech by Houthi leader Abdul Malik al-Houthi, who reiterated the group’s intent to persist in its operations against Israel. The Israeli military emphasized its resolve to carry out further strikes as needed, despite the significant distance between the two regions.
