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

A Houthi political official says the group will continue attacking Israel in solidarity with the Palestinians despite the escalating Israeli air strikes in Yemen.Mohammed al-Bukhaiti told the BBC that the Houthis would "escalate our military targeting of Israel" until it stopped what he described as "the genocide in Gaza".

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.
