According to Yemen’s al-Masirah TV channel on Monday, the artillery fire targeted the villages in the al-Dhaher district of Sa'ada.
There was no immediate report on possible casualties or damage.
This came one day after Yemen’s army and fighters from the Popular Committees repelled a major attack by Saudi-backed militants in the southwestern province of Taiz.
The Saudi-led coalition invaded Yemen in 2015. Since then, over 100,000 people have been killed, according to the US-based Armed Conflict Location and Event Data Project (ACLED).
The Saudi-led aggression and an accompanying blockade of Yemen continue despite the coronavirus pandemic and the impoverished country’s urgent need for medical supplies.
