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 struck multiple targets in Yemen it said were controlled by Houthis, the last of the Iran-backed groups still fully engaged in the regional war that began 14 months ago.
