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.

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 launched a multi-wave attack across Yemen in retaliation for Houthi missile and drone strikes, the Israeli military confirmed Thursday.
