The fighters said many civilians were killed or injured after Saudi warplanes dropped phosphorous bombs on villages in north.
They have also released pictures of phosphorus bomb attacks by Saudi warplanes.
In a move to protect the civilian population from the raging war in north Yemen, Amnesty International wrote a letter to Saudi Arabia's Defense Minister, Crown Prince Sultan bin 'Abdul 'Aziz Al-Saud last week asking whether phosphorus bombs were used in the attacks.
The London-based rights group demanded Riyadh's explanation about the manner in which the bombs were used and what precautions were taken to ensure that civilians were not put at risk.
The organization however has received no response from Saudi officials yet.
Saudi Arabia launched earlier in November an offensive against Shia fighters, who accuse the kingdom of supporting the Yemeni government in its crackdown.
The Yemeni government launched Operation Scorched Earth in August in an effort to crush the Houthis, whom it accuses of seeking to restore an imamate that was overthrown in 1962.
The Houthis, however, dismiss the accusations, saying they are only seeking to put an end to the government's discriminatory policies against them.
The fighters said many civilians were killed or injured after Saudi warplanes dropped phosphorous bombs on villages in north.
