Saudi Foreign Minister Adel al-Jubeir has said that Iran send military experts to Yemen.
In a press conference held in Munich, Germany, al-Jubair stressed that Iran intervenes in affairs of other states and sending arms and fighters to them.
He said that Iran's behaviors in Yemen make it a part of the problem, not a part of the solution, making reference that the Yemeni crisis would be ended this year.
He further emphasized that there is a deal stricken between Iran and ISIS and al-Qaeda, wondering why Iran is the only country in the region which is not attacked by these terrorist groups.
He made reference that the Houthis have not committed to any agreement and that they refuse any deals.
He also cited that the international community has many ways to put an end to Iran's acts which include, according to him, the ban of travel, and the ban on Iranian banks and companies' dealings.
Governor of Saadah province Hadi Tarshan al-Waili has said that militias of the Iranian Revolutionary Guards and the Lebanese Hezbollah have largely increased in Saadah.
Tarshan affirmed that Iranian military experts give consultations to the Houthis on the ground, pointing out that some of them are specialized in industrializing explosives and missiles.
He said that some elements of the Iranian Revolutionary Guards were captured in Saadah, al-Jawaf and Aden.
The Saudi-led Arab Coalition last week killed five Iranian experts along with a number of Houthis in the area of Saqain, Saadah governorate.
A Saudi newspaper quoted a tribal source as saying that the coalition destroyed rocket launch bases, arm depots and military supplies in the districts of Kitaf and Haida.
The source said that dozens of the Houthis' corpses were brought to the governorate of Saadah in the past few days, pointing out that the Houthis lost hundreds of their fighters in Mocha.
Furthermore, the Yemeni army managed last month to seize Iranian-made rockets which were used by forces of the Houthis and ousted President Ali Abdullah Saleh.
Spokesman of the Popular Resistance in Saadah Abdullah al-Shandaqi told al-Sharq al-Awsat newspaper that the Yemeni army backed by the popular resistance managed to capture weapons and other military supplies.
Warships from the US Navy have intercepted several weapons shipments sent by Iran to the Houthi rebels in Yemen.
