TEL AVIV, Israel — The rockets from Gaza have mostly fallen silent. A ceasefire with Hezbollah militants in Lebanon has taken hold. But repeated fire from Yemen’s Houthi rebels, a faraway foe, is proving a stubborn threat for Israel.

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

The US military on Tuesday said it hit targets in Yemen targeting the Houthi militia, hours after the Iran-backed group launched attacks on Israel. The United States Central Command (CENTCOM) said its warships and aircraft attacked a number of Houthi-linked sites,

The US THAAD system is under fire after another reported failure to intercept Houthi missiles in Israel. Houthi official Nasruddin Amer reportedly mocked US and Israeli defences, claiming no system can counter hypersonic missiles.

A missile launched from Yemen by Houthi rebels crossed into Israeli territory, prompting air raid sirens in Jerusalem and central Israel. The missile was successfully intercepted by the Israel Defense Forces (IDF) with fragments falling near Modiin.

Missile shrapnel fell in Modi'in in central Israel, although there were no immediate injuries or damage reported, the military said. Meanwhile, German Foreign Minister Annalena Baerbock is in Syria. DW has the latest.
