"The Saudi government's use of weapons which contain toxic and pathogenic gases in air and missile strikes against residential areas is aimed at genocide and breaking the legitimate resistance of the brave Yemeni people," Shamkhani said in a meeting with a delegation of Yemen's high council of revolution in Tehran on Tuesday.

He also described massacre of innocent Yemeni women and children and the inhumane siege imposed on the nation by the Saudi-led coalition as a war crime, and said, "Negotiations among Yemeni groups and preventing foreign meddling in the country is the only way to create understanding and restore security and stability to Yemen."

The head of the Yemeni delegation, for his part, appreciated Iran's effective support for the Yemeni people, and underscored his country's firm resolve to fight against the foreign aggression.

In relevant remarks in June, a senior leader of Ansarullah revolutionary movement blasted Saudi Arabia for its continued use of internationally prohibited weapons, including chemical ordinance, against the Yemeni people.

"Saudi Arabia is still using chemical bombs against the Yemeni people," Hashem Adnan al-Basouri told FNA.

He underlined that Riyadh hits residential areas under the control of Ansarullah with chemical weapons.

"A report by the human rights watch showed that Saudi Arabia has used poisonous gas in four airstrikes on different parts of Sa'ada province," al-Basouri added.

Saudi Arabia has been striking Yemen for 195 days now to restore power to Hadi, a close ally of Riyadh. The Saudi-led aggression has so far killed at least 6,445 Yemenis, including hundreds of women and children.

Hadi stepped down in January and refused to reconsider the decision despite calls by Ansarullah revolutionaries of the Houthi movement.

Despite Riyadh’s claims that it is bombing the positions of the Ansarullah fighters, Saudi warplanes are flattening residential areas and civilian infrastructures; FNA reported.
