Saudi Arabia on Sunday accused Iran of blocking peace efforts in Yemen, slamming its political archrival over support for the Yemeni rebels Riyadh is fighting against.
Saudi Foreign Minister Adel al-Jubeir accused Tehran of smuggling arms to Yemen's Shiite Huthi rebels, who control northern Yemen, and to the rebels' ally former president Ali Abdullah Saleh.
"Iran is destroying all attempts to find a solution in Yemen, which has led to the failure of all political negotiations between the government and these militias," Jubeir told a gathering in the Saudi capital of foreign ministers and military officials from countries including Egypt, Bahrain, the United Arab Emirates and Senegal.
"These militias would not have continued operations without the support of the greatest sponsor of terrorism in the world -- the Iranian regime," Jubeir said.
Sunday's gathering in Riyadh comes a week after US Secretary of State Rex Tillerson met with Gulf officials in the Saudi capital for talks that largely focused on Iran's role across the region.
