Taha Ahmed Al-Mutawakil made the announcement on Tuesday, saying that 236 people also were injured in the coalition's airstrike on the prison.
The spokesman of Harakat Hezbollah al-Nujaba Nasr al-Shammary stated that these incidents are a crime against humanity and a massacre.
It is the natural and legitimate right of the Yemenis to defend themselves and respond to any aggressions imposed by other countries, al-Shammary added.
Saudi Arabia, at the head of an Arab coalition backed by the United States, launched a military aggression against Yemen and imposed a land, air and sea blockade on March 26, 2015, in a bid to bring the ousted and fugitive Yemeni president Mansur Hadi back to power.
