Story highlights Saudi-led coalition carries out 130 airstrikes in 24 hours

A U.N. official calls it a breach of international humanitarian law

A coalition spokesman says Houthi rebels used civilians as human shields

(CNN) A Saudi-led coalition rained down missiles in Yemen from Friday into Saturday, an intense attack that a U.N. official called a breach of international humanitarian law.

The Saudi Press Agency reported that the latest attack against Houthi rebels in Yemen -- 130 airstrikes in a 24-hour period -- included the targeting of schools and hospitals.

The hospitals and schools that were hit functioned as weapons storage sites, coalition spokesman Brig. Gen. Ahmed Asiri said in a statement.

Asiri told CNN later that the press agency had mistranslated his words, and denied that the coalition has struck schools or hospitals.

"Someone asked me about how they (Houthis) have weapons if we destroyed so many of their depots," Asiri said. "I told him they are hiding them in hospitals, schools and hotels and they bring them out and use them."
