The spokesman of the Saudi-led coalition battling Yemen's Shiite rebels says there will be no extension to the 48-hour cease-fire, which neither of the two warring sides observed.

Gen. Ahmed al-Assiri told the Dubai-based Al-Arabiya network on Monday that the cease-fire won't be extended. The coalition had declared the truce on Saturday.

Fighting has not stopped along any of Yemen's front lines. Clashes have been especially intense in the war-torn western city of Taiz, where the rebels known as Houthis and their allies have been besieging forces loyal to the internationally-recognized government of President Abed-Rabbo Mansour Hadi, which is supported by the coalition, for about a year.

The coalition resumed airstrikes on Monday the capital, Saana, the eastern cities of Marib and Jouf and the northern border area of Medi.
