Saudi Foreign Minister Adel al-Jubeir is accusing Tehran of smuggling arms to Yemen’s Shiite Houthi 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 tells 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 says.

The Yemen war has claimed more than 8,600 lives since a regional military coalition, led by Saudi Arabia, joined the Yemeni government’s fight against the rebels in 2015.

A cholera outbreak has also claimed more than 2,100 lives since April as hospitals struggle to secure supplies amid a blockades on ports and the country’s main international airport.
