Saudi-led warplanes carried out new strikes on an arms depot in the rebel-held Yemeni capital on Tuesday, hours before a five-day cease-fire were scheduled to begin.

It was the second straight day that the coalition had hit the depot in a military base on Mount Noqum in the eastern outskirts of Sanaa.

Twin strikes on Monday killed at least five people and wounded 20, as huge explosions sent debris crashing into a residential area at the foot of the mountain.
