CAIRO — A spokesman for Saudi Arabia’s military said Saturday that 10 Saudi soldiers were killed in a rebel missile strike a day earlier in Yemen, raising the death toll from the attack to at least 60.

It was the first public acknowledgment by the Saudis that they have ground troops in Yemen, where they are leading a coalition to roll back gains by the Shiite rebels known as Houthis and their allies.

The United Arab Emirates said 45 of its soldiers were killed in the attack on Friday, when rebels hit an ammunition depot in Marib Province, about 75 miles east of the capital, Sana. It was the deadliest day for the military in the nation’s 44-year history.

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