Israel's navy attacked docks in Yemen's rebel-held port city of Hodeida on Tuesday, launching its first seaborne assault against the Iranian-backed Houthi rebels while warning more could come. The attack on Hodeida likely damaged facilities that are key to aid shipments to the hungry, war-wracked nation, but also have allegedly been used for weapons smuggling as vessels reportedly bypass United Nations inspectors. Both Israel and the United States have struck ports in the area in the past — including an American attack that killed 74 people in April — but Israel is now acting alone in attacking the rebels as they continue to fire missiles at Israel over its war on Hamas in the Gaza Strip.
