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?

Yemen's Houthi rebels say Israel attacked docks in the port city of Hodeida, likely damaging facilities that are key to aid shipments to the hungry, war-wracked nation.

Israeli navy ships have struck targets in the port city of Hudaydah in Houthi-controlled Yemen. The Israeli military said in a statement the strikes were carried out in response to Houthi missiles targeting Israel and were aimed at stopping the use of the port for "military purposes".
