At least 30 Yemeni government troops were killed in attacks on military camps in the Marib and Hadramout provinces on Thursday.

Axar.az reports, citing Reuters, that the Iran-aligned Houthis later claimed responsibility for missile and drone strikes targeting Saudi military deployments in the two provinces.

The Houthis said they struck Saudi troop concentrations in the Al Ruwayk, Al Abr and Al Thaniyah areas with ballistic missiles and drones, claiming that hundreds of Saudi-aligned fighters were killed or wounded and that military camps, weapons depots and vehicles were destroyed.

The group said it launched the operation after detecting a large Saudi military buildup ahead of an escalation against areas under Houthi control.

The U.S. Mission to Yemen condemned the attack.
