Yemen's Houthi rebels, who were threatened with an air and naval blockade by Israel on Tuesday, are one of Iran's few allies still standing since the Gaza war spilled across the Middle East. WHAT IS THE HISTORY OF THE HOUTHIS?

The Israeli navy has attacked docks in Yemen’s rebel-held port city of Hodeida, likely damaging facilities that are key to aid shipments to the hungry, war-wracked nation.

The Israeli navy struck the Yemeni port of Hodeida on Tuesday using missile ships, the military said, adding the attack was in response to recent launches by Houthi rebels towards Israeli territory.
