Israel struck Houthi militias in the Yemeni capital of Sanaa on Thursday, the Israeli military said, in the second such assault on the city in less than a week.
Residents told Reuters the attacks struck an area near the presidential complex and a building in southern Sanaa.
Yemeni military sources said the presidential complex housed an operations room and a missile storage facility used by the Iran-aligned militants.
An Israeli military statement referred to a single attack.
Israeli security sources said it had targeted various locations where a large number of senior Houthi officials had gathered to watch a televised speech recorded by leader Abdul Malik al-Houthi. But a source from the Houthi Ministry of Defense denied reports of leaders being targeted in Sanaa, the Houthi-run news agency reported.
"Whoever raises a hand against Israel - his hand will be cut off," Israeli Defense Minister Israel Katz said in a statement on Thursday.
The strikes followed Israeli airstrikes in Sanaa on Sunday, killing at least 10 people. The Israeli strikes hit an oil facility owned by Yemen’s main oil company, which is controlled by the Houthis, a power plant and a military site in an area where the presidential palace is located, according to the Houthis and the Israeli military.
The strikes are the latest in more than a year of attacks and counterstrikes between Israel and Houthi militants in Yemen, part of a spillover from the war in Gaza.
