A missile attack by Shi’ite Houthi rebels hit a Yemeni army base in Marib on Saturday killing 70 troops and wounding scores more. Yemeni officials confirmed the attack at the base 70 miles (115 km) east of the capital of Sanaa.

The soldiers were gathered in a mosque conducting evening prayers when the missiles hit. According to the official SABA news agency, Yemen’s president, Abd Rabbu Mansour Hadi condemned the “cowardly and terrorist” attack. 

“The disgraceful actions of the Houthi militia without a doubt confirm its unwillingness to (achieve) peace because it knows nothing but death and destruction and is a cheap Iranian tool in the region,” Hadi said.

Saudi Arabia’s Al Ekhbariya television quoted sources as saying the assault was carried out with ballistic missiles and drones, killing 60 military personnel and wounding dozens of others. That number was raised to 70 as officials at the Marib city hospital updated it since more and more victims were being treated there.
