AFP-- "The Saudi foreign minister's claims that our country has been blocking peace efforts in Yemen are ridiculous and baseless," foreign ministry spokesman Bahram Ghasemi said.
"Iran has condemned the aggression (against Yemen) since the beginning... and will not spare any efforts to stop this bloody and detestable war," Ghasemi said in a statement published on the ministry's website.
Saudi Arabia leads a military coalition backing Yemen's former government in its fight against the Shia Huthis.
Both sides in the Yemen conflict have come under harsh criticism for their neglect of civilian safety, but the Saudi-led coalition is in particular bombing schools, markets and hospitals.
"Repeating such false accusations will not reduce the responsibility... of those who have committed heinous crimes, particularly murder, destruction of schools and hospitals and pushing an innocent population to famine," Ghasemi said.
On Sunday, Saudi Arabia's top diplomat -Adel al-Jubeir-accused Tehran of smuggling arms to the Huthis, who control northern Yemen, and to their allies.
