Fighting between Yemen's internationally recognised government forces and Houthi fighters has intensified across several fronts, causing casualties and worsening an already severe humanitarian crisis.
The escalation follows Houthi territorial gains along the Red Sea coast last month and a Saudi-backed government counteroffensive aimed at reclaiming lost territory.
Eight government soldiers were killed in fighting on the al-Maqatirah front in Lahij governorate, military officials said Saturday.
In Taiz, government forces reported killing 12 Houthi fighters in al-Aqroud and repelling attacks near Taiz city and al-Shaqab.
Government-aligned forces also reported drone and precision strikes against Houthi positions in al-Wazziyah and al-Madaribah.
Fighting continued in al-Jawf and Marib, where government forces and coalition aircraft targeted Houthi positions, command facilities and supply depots.
The operations form part of the government's Dawn of Yemen campaign, which seeks to recapture Houthi-held territory, including Sanaa.
Meanwhile, the Houthis claimed to have downed a Saudi Apache helicopter in Najran.
Coalition spokesman Turki al-Maliki disputed the claim, saying an AH-6i reconnaissance helicopter crashed because of a technical malfunction, killing two crew members.
The Houthis also claimed to have downed a Saudi reconnaissance drone over Hajjah.
Separately, armed attackers fired at an LNG tanker off al-Mukalla before withdrawing following warning shots from onboard security personnel.
The International Organization for Migration reported more than 233,000 displaced people, including approximately 121,000 in Taiz.
The World Health Organization warned that Taiz city's 12 hospitals face severe shortages of fuel, oxygen, medicines and surgical supplies amid a cholera outbreak.
More than 4,000 refugees have reached Djibouti and Somalia, according to UNHCR.
Djibouti's Markazi camp has recorded 31 cholera cases and one death.
The International Committee of the Red Cross confirmed the release of 159 detainees by the Houthis, who said 323 prisoners had been freed under an amnesty.
Gulf Cooperation Council Secretary-General Jasem Mohamed Albudaiwi called for a coordinated international response to Houthi attacks and urged Iran to comply with international law.
