Israel is signaling a wider campaign against Houthi militants in Yemen, a mountainous and impoverished country more than 1,000 miles from Israeli territory.

An official says the Yemeni group will not stop until the war in Gaza ends, as Israel's PM says it is "just getting started".

The head of the World Health Organization said he was about to board a flight in the Yemeni capital when the airport came under bombardment.

Israel has severely weakened Hamas and Hezbollah. Now it's going after another member of Iran's so-called axis of resistance: the Houthi rebels of Yemen.

A new round of Israeli airstrikes in Yemen on Thursday targeted the Houthi rebel-held capital and multiple ports, while the World Health Organization's director-general said the bombardment occurred nearby as he prepared to board a flight in Sanaa,

Israel's air defence intercepted a missile fired from Yemen early on Saturday, according to the military. The missile was shot down before it could reach Israeli territory, the military said on Telegram.

An advanced U.S. military anti-missile system was used in Israel to try to intercept a projectile for the first time since President Joe Biden placed the system in Israel in October, a source familiar with the matter told Reuters on Friday.

The Israel Defense Forces claimed responsibility for a series of airstrikes in Yemen on Thursday it claimed were targeting Houthi military infrastructure.

Israel launches waves of attacks across Yemen in retaliation for Houthi missile and drone strikes Israeli newspaper Haaretz reported that Israel Defense Forces warplanes hit Sanaa International Airport in the capital, which is controlled by the Houthis. Sources in Yemen also reported strikes on the port city of Hodeida.

World Health Organization chief Tedros Adhanom Ghebreyesus was about to board a plane at the Sanaa International Airport when it came under attack. A crew member on the plane was injured, he said.
