The cessation of hostilities was welcomed but “is threatened by Houthi violations, including military operations, mobilization of troops and vehicles, and drone strikes,” Foreign Minister Ahmed Awad bin Mubarak wrote on Twitter.
The army also accused the insurgents of violating the ceasefire by attacking several regions.
On various combat fronts, the militia used heavy and light weapons as well as drones, said a military statement, which reported operations in Hays, Maqbana, Ahtoob and Kadaha areas.
For their part, the Houthis warned of dozens of reconnaissance plane raids in Marib, Hajjah, Saada and Lahj provinces.
According to the rebels, at least 36 rocket and artillery bombardments were counted against their positions, although this data has not been verified.
The cessation of hostilities came into effect last Saturday after negotiations led by UN Special Envoy for Yemen Hans Grundberg.
The deal provides for the suspension of “all offensive air, land and sea military operations within and beyond Yemen.” The last sentence refers to the militia’s systematic drone and missile attacks against targets in the United Arab Emirates and Saudi Arabia, whose authorities support Yemeni President Abd Rabbu Mansour Hadi.
Last week, the Houthis announced a three-day unilateral ceasefire, to which the Saudi authorities responded with a similar one during celebrations of Ramadan, the Muslim holy month.
The war began in 2014 when the rebels took up arms and occupied large parts of the country, including the capital Sanaa.
The following year, a Saudi-led Arab coalition intervened in the conflict to support Hadi.
According to the Office of the United Nations High Commissioner for Refugees, two-thirds of the population, around 20 million people, are in need of humanitarian assistance and 80 percent live below the poverty line.
