Battles between the pro-government forces backed by the popular resistance and the Saudi-led coalition and the Houthi militants continued in several Yemeni provinces including Baidha and Taiz on Monday.
Local sources said pro-government fighters raided positions of the Houthis in the town of Rada'a, Baidha, sparking fierce battles all the day.
Many were killed and injured from both sides, they said, without giving statistics.
The battles in Baidha started in late 2014 after the Houthi militants ousted the government.
The militants have been unable to take control of this province because of strong resistance by the pro-government tribes.
In Taiz, local sources said the Arab military coalition targeted areas in the town of Al-Rahida where the Houthis planted landmines to prevent the pro-government forces and resistance from advancing toward the city.
The forces have retaken the town after fierce battles in recent days.
A week ago, the Yemen forces with support from the coalition launched an offensive to drive the Houthis of Taiz.
In downtown and western parts, battles have been raging with hundreds of fighters from both sides killed and injured.
Lately, battles have also erupted in the province of Ibb where the pro-government fighters are still tightening their grip on most parts.
The Saudi-led coalition has been striking the militants in support of the government forces since March.
In the past 24 hours, it resumed airstrikes against Houthi military camps and weapons depots in the capital city of Sanaa.
