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.

Thousands of Yemenis gathered on Friday (December 27) in the capital Sanaa, to protest against the Israeli airstrikes carried out the previous day on Yemen, and to show solidarity with Palestinians in Gaza.

Israel has banned the pan-Arab Al Jazeera network and accused six of its Gaza reporters of being militants. The Qatar-based broadcaster denies the allegations and accuses Israel of trying to silence its war coverage, which has focused heavily on civilian casualties from Israeli military operations.

The United States said it struck targets in Yemen's rebel-held capital in December, hours after a Huthi rebel missile wounded people in Israel. But a nighttime picture of a massive fire repeatedly shared on social media does not show the US strike.

An Israeli strike on the international airport in Sanaa, Yemen, on Dec. 26, killed at least four people, according to local media. Houthi attacks on Israel have ramped up in recent weeks.
