SANAA, Yemen: Saudi Arabia’s military said Saturday that 10 of its troops were killed in a rebel missile strike a day earlier in Yemen, raising the death toll in the attack to at least 55 coalition troops killed in action against Houthis and their allies.

The United Arab Emirates lost 45 troops in the attack Friday, when rebels hit an ammunition depot in Marib, about 120 kilometers (75 miles) east of the capital, Sanaa. It was the deadliest day for the UAE’s military in the nation’s 44-year history.

“Ten Saudi soldiers from the Arab coalition forces were martyred,” in the attack on the weapons depot, Saudi military spokesman Brig. Gen. Ahmed Asiri said in a statement.
