Red Sea crisis: US launches fourth round of strikes on Houthis in Yemen

US missile strikes came after a bulk carrier was hit by Houthi drones in the Gulf of Aden

The US military has fired another wave of missile strikes against Houthi-controlled sites, marking the fourth time in a week that it has directly targeted the group in Yemen.

The strikes were launched from the Red Sea, hitting more than a dozen sites - the officials told the AP news agency - and came after a drone launched from areas controlled by the Houthis hit a US-owned vessel in the Gulf of Aden.
