The Yemeni government said that "20 Houthi fighters, including military leaders, were killed in battles with government forces in the governorates of Al-Bayda, Marib and Al-Jawf."
In turn, Houthi media said that the planes of the Saudi-Emirati coalition launched 18 raids on sites in the Marib and Al-Bayda governorates.
The army's media center said that its forces repelled a Houthi attack in the Jadafer area in Al-Jawf governorate, and that coalition warplanes destroyed two military vehicles and killed those in them.
He added that the army launched a counterattack on Houthi sites in the northwest of Ma'rib governorate, hours after it repelled a Houthi attack on its sites, and that the Houthis had suffered heavy losses, which he described.
In Al-Bayda Governorate, central Yemen, military sources said that violent confrontations erupted in the districts of Al-Soma and Al-Zahir, after the Houthis resumed their attack on the positions of the army and local resistance forces, with the aim of restoring the sites that fell last week.
For nearly 7 years, Yemen has been witnessing a war that has killed 233,000 people, and 80% of the population of about 30 million people have become dependent on aid to survive, in the worst humanitarian crisis in the world, according to the United Nations.
The conflict is further complicated by the fact that it has regional extensions. Since March 2015, an Arab coalition led by neighboring Saudi Arabia has been carrying out military operations in support of government forces in the face of the Iranian-backed Houthis who control several governorates, including the capital, Sanaa.
