Local security officials say Houthis were killed in a military air raid in the northern province of Jawf on Wednesday.
The casualties come after Yemeni air force hit the house of a pro-government tribal leader which was stormed and held by Houthi fighters.
In a separate development, at least ten people were killed and dozens more injured in a confrontation between government forces and protesters southern Sana’a.
Thousands of Houthis and other revolutionaries have been staging protests in the capital city of Sana'a for nearly a month with angry revolutionaries accusing the government of corruption and urging its resignation.
On Monday, the Houthi leaders said they had suspended their participation in talks with the government over what they called foreign intervention in the negotiations.
Rupert Colville, the spokesperson for the UN High Commissioner for Human Rights, has urged Yemeni officials to probe the recent killing of protesters in the country’s capital.
“As Yemen faces various internal challenges, it is more crucial than ever that violations of international human rights law are not swept under the carpet,” media outlets quoted Colville as saying.
Shia Houthi protesters have been holding demonstrations since August 20 in a bid to press the government of Yemeni President Abd Rabbu Mansour Hadi to quit. They say the government is corrupt and marginalizes the country’s Shia community.
The Houthi movement played a key role in the popular revolution that forced former dictator Ali Abdullah Saleh to step down in February 2012.
