The Saudi-led coalition has denied as "groundless" reports it carried out an air strike on a prison in Yemen's rebel-held north that aid groups said killed at least 70 people, including migrants, women and children.

Saudi Arabia accuses regional rival Iran of providing military support to Yemen's Huthi rebels, especially missiles and rockets, claims that Tehran denies.

"The continuation of the coalition's military attacks on Yemen with the silence and indifference of the international community and the uncontrolled sale of weapons to the aggressors... has made the path to achieve a just peace in the country even more difficult," foreign ministry spokesman Saeed Khatibzadeh said in a statement.

The latest violence in Yemen's seven-year war came after Huthi forces on Monday claimed their first deadly attack on Abu Dhabi, capital of the United Arab Emirates, a member of the coalition.

The attack, which coincided with a coalition strike on Hodeida that killed three children and knocked out Yemen's internet, was condemned by the United Nations secretary-general.

Khatibzadeh said there was a lack of "serious determination to advance the political settlement of the Yemeni crisis", warning it will lead to the "destruction of the country and instability in the region."

The Huthi rebels seized the capital Sanaa in 2014, prompting the Saudi-led intervention -- supported by the US, France and Britain -- in March 2015.

"The countries that provide the coalition with bombs and weapons of mass destruction are complicit in these crimes and must be held accountable," Khatibzadeh added.
