The Arab coalition said it intercepted and destroyed on Saturday a booby-trapped Houthi drone targeting the Saudi city of Khamis Mushait.

The coalition is taking strict measures to protect civilians, the coalition said.

The attacks come a day after the newly appointed UN special envoy for Yemen Hans Grundberg told the Security Council that the offensive on Marib must stop.

“Civilians, including the many internally displaced persons who sought refuge in Marib, live in constant fear of violence and renewed displacement,” the official said.

“The UN and the international community has been clear in its message: The offensive must stop,” Grundberg said.

Houthis say the missile and drone attacks are part of the self-defence an in response to the coalition airstrikes on Yemen.
